Well hello rocketrm2. Although I probably wouldn't have seen you on the trail, I reckon you would our seen our names in the logs books.
We started on the 7th and just finished on Tuesday the 18th, also going east to west.
I too had some notes for others planing to walk in 2016. So hopefully you don't mind me tacking these words on the end of your thread for the benefit of others

1) Don't walk at noon
By our 3rd day we found that walking between 11am and 3pm to be possible but very undesirable. Especially on the 25C+ days (I cant imagine how bad it would be on those 30C days, the lack of shade in some sections really was a game changer for us).
So our typical days went a bit like this:
75% of our walking was done from dawn (or earlier) to 11am
We found some
solid shade (typically river beds with ghost gums) before noon and cooked our big meal, plus did any other housekeeping and maybe have a nap. (Note. this may not be a problem during June-July)
Then from about 3or4pm up to twilight we walked another 25%. We were fond of just finding any suitable spot to camp (read: un-marked camp sites), such as at the base of Spencer gorge. There really were an abundance of these spots to pull up and sleep (assuming just one small tent).
Some nights we used headlamps to keep pushing forward in the cool air.
2) Shoe failure?
I wore dunlop KT-26 and they were fine. My partner had some merrel trail runners, also fine.
I had read a lot of warnings about shoe failure and/or bruised feet on this trail. To the point where I was unnecessarily concerned about it but it's simply a non-issue!
To any potential 2016 walkers, just use common sense for footwear (boots or runners). If you live in Vic; checkout Werribee Gorge and Cathedral Ranges to get an idea.
I think it's the 220+km combined with a heavy pack that will cause problems, not necessarily the sharp rocks.
3) Gaiters/spinifex
We didn't take gaiters and we were glad. I just didn't see the spinifex as major problem, although we were wearing long pants (for sun protection). Just the occasional misplaced foot would result some spikes getting through and even then it was nothing to worry about... perhaps in a different season their ends are sharper?
The buffel grass burr seeds were the worst! In sections with this grass; do look before you sit down or you will end up with 100s of them in your clothes.
4) Suggested times
The times found on the parks NT descriptions and chapman book were about on par and not ridiculously inflated, especially with a heavy pack and walking when hot.
But once we hit our stride (about after day 6 for us) with lighter packs, we were starting to the cut the times in half.
5) Food
We had estimated 800g of food per person per day. Instead we were eating roughly 400-500g
Note to self, dont take too much food next time

Note to others: Vitafresh sachets were our favorites
6) Water
We did section 9 (the dry section) from about 3pm to 11am and drank only 5-6L (between 2 people) of the 10L we carried.
(Also camped deep in the gully of Waterfall Gorge, probably our favorite camp all up)
The other sections needed even less in water, which meant a lot of weight savings.
7) East to west
Since 75% of our walking was done in the morning, it meant we didn't have the sun in our eyes most of the time. This would be my greatest argument for east to west traveling.
8 ) Mid-August (shoulder season)
June July seems to attract the most number of walkers (not great if you prefer solitude), plus the mornings can easily be below freezing.
Mid August can be a gamble with the afternoon temp: It can reach 30C (luckily we didnt get any days above 26C), so there is more reason to not walk during midday, but at least you get a bit more day light each day.
9) Ormiston gorge
We found that the pound walk wasn't that unique compared to the rest of the trail and could be skipped; although the gorge itself was well worth the time.
The kiosk offer the use of their phone for $1 per minute, which was great to call Alice Wanderer to ask them to pick us up 2 days earlier than scheduled (although hitching a ride would also be a cheaper and more convenient method of getting back back to alice springs if you are into that).
The campsite wasnt that nice in our opinion so we left before sunset and found a nice river bed to sleep in 1h or so to the west.
10) Brinkly bluff
My partner's Iphone 5 manged to just get reception on the optus network from Brinkly Bluff which was great to get a weather forecast.
My nexus 4 on optus did not get reception

We didn't get any wind up there while camping... must have been pretty lucky
11) A dingo didn't steal my baby!
But it did steal someone else's food. See my other post if interested:

12) Food drops
We should have got the food drop at Standly Chasm to save a few kg on the first few days (our hardest days). Alice Wanderer offers it with no problems or fuss.
Also I found Alice Wanderer was the cheapest provider and got the job done
13) Larapinta trail was the best
We had the time of our lives on this trail. If you are considering going; please do, its an amazing place and I'm so sad I'm not back out there right now. I cant put it to words just how special it was.
I would love to go back again... maybe even when the rivers are flowing (only once every decade or so I hear)
