Hi
Well I have a decent chance to give the Styx 2 a decent work out over eight days on the Western Arthurs in SW Tassie. As this walk is rather up and down I decided that a fitness campaign was required plus doing a few more of the harder climbs with bit more air under the feet to deal with the growing fear of heights that has crept up on me. So Cradle bagged along with Barn plus David's Peak and overnight walk every weekend form the last weekend in December to the first one in February. But as they say the plans of mice and men can be stuffed up. Three weeks out on a ride to Montezuma Falls a flat tire pitched me over the handle bars and cost a trip to x-ray on the return. So with a least one or two cracked ribs the long planned trip looked off. Unknown to me two weeks out a fellow walking companion on "test" walk on the Penguin to Cradle trail managed to stretch an Achilles tendon but never under estimate walker stubbornness as we both attempted the trip hoping not to disappoint or hold up the two uninjured members of the party.
Well it was not until a day before WA day that I risked putting on the loaded pack. Try as I may I could only get the weight down to 26 kilograms. Ok, UL or even moderately light weight I am not. Almost pulled the pin but as the walk to Junction Creek was suppose to be flat and easy took the punt with full intention of camping there and awaiting the return of my walking companions if the next day I could not go on. The Exact Fit harness like magic dodged the extremely sensitive area and spread the load so I found myself completing the trip.
I found that I was underdone on water (only 1.6 litres when 3 litres would have been better) and the decision to dump the Crocs as camp shoes was not one that I will do again as it rather turned my walking companions into go fetch boys so needless to say I coped some ribbing

I managed to fit into the 75 litres so tends to reinforce my view that even as a luxury loving walker of the XXL sizing a 75 litre pack is now the 90 litre pack. Though I always will own a McMillan as it is just one great pack for carrying anything I can.
The good. The harness is simply for me superb. The bottle holders just wonderfully placed on the harness and nothing broke. The bad. Well not a fan of the diagonal zip and can not see the point of the bottom compartment so loved by sales people. Save a few grams and some money and get rid of it is my feeling. But at least OP have the best system with an inner pocket that can use the space of the main compartment or be push out of the way if you chose to use the bottom compartment. I found that the new sliver shoulder straps would slip where the older black ones with yellow stitching never did. And yes, as tough as the canvas is, I managed to put some abrasion holes in. The pack is not as well protected as the McMillan. But I add the holes were to be expected given that in the tricky sections I gave no regard for pack and was more than happy to slide down on it rather than risk any life or limb. In fact, the damage was remarkably light given the abuse of 25 kilograms of pack plus 110 kilograms of me sliding down a rocky slope.
In all I loved it but for that terrain probably would prefer the Stiletto. In fact sorely tempted with a Stiletto minus the unnecessary for me bits. Ice axe holders, etc.
Now I mentioned to OP the slipping shoulder straps buckles and was quizzed on what I was doing. They had no issue with the new material and were puzzled so asked me to send the pack to them. One Planet's after sales service is awesome once you get to the right person. Anyway, I was a bit slack sending it so got a follow up call. The problem was identified. The supplier of the new strapping had snuck an under width and thickness lot in and this combined with the new buckle had caused the issue. Please send the pack to get the strapping swapped over. I have the same material on my McMillan when it was retro fitted with an XL harness and that has worked a treat so pretty confident that when returned the pack will not have that issue. Also One Planet was more than happy to make good the abrasion damage at a very reasonable cost. It is great having the ability to get the pack back into A one order rather than to have an average patch up job.
So what can I say. Amazing harness and the best of the traditional designs which is needed on tricky tracks like the WA where I want to hug the rocks. Would prefer it to be better armoured but then again just about anyone but me would have been unlikely to damage it unless they are into sliding down every drop. Probably would buy a Stiletto instead but they for some reason rather hard to come by, and the Styx 2, like a lot of my local purchases was an impulse buy. Took the McMillan in for the recent site overnight walk and found it huge with it been rather empty so looks like I have transition to more compact gear. It does lead me to think that there might be a market for a 70-75 litre Mungo style but armoured like a McMillan or Stiletto for the tougher walks. Sure it will not set any light weight saving records but there will always be room for a tough pack at least in Tassie.
Interesting on the trip was looking at the range of gear we used. I was rather traditional in my choice so tipped the heavy scales. One of our group was light weight to UL with a Go-Lite Jam and largely the gear choices required to make that work. The other walker had a OP McMillan but with some lighter weight gear choices. The Jam was treated with kid gloves by the owner and there is merit in lighter weight as easier to hand down and up. Despite this it suffer a hole or two but nothing worth worrying about. The McMillan was given no special treatment but it owner was somewhat more agile and lighter than me so it go an easier time. It was undamaged. Sadly the OP Shadow owner had to pull out as on the way to Junction creek he encountered the dangerous of the most dangerous thing, a slippery board walk, thus meant that he pulled is Achilles again and decided on safety first but still a few days later covered a lot of territory as day walks.
And OP service is great but could someone at Mountain Design please tell me why every time you take over a independent store you stop stocking One Planet packs

As proud as you might be of your own packs in your range there is nothing like OP's coverage of the pack market. In fact with the demise of the Launceston shop stocking them I find MD no longer a compulsory stop to feed my gear freak side.
On a different note, the most dangerous thing on the WA was the training before it
Cheers
