But both points of view are worth noting (numbers do not necessarily equate to wisdom

), you just need to decide which way your own priorities and practices are best suited. In particular, if you are buying all new gear, you may be able to buy gear that more easily fits into a smaller pack than those of us who have older bulkier gear (and can't justify replacing it all before it wears out).
Though i'm sure they would agree that 'Yes' the pack size you mention would indeed "be suitable for walks such as the Overland Track"....especially if it true to size
Absolutely (as I said in my initial post in this topic)! For 5 days (or so) on the OT, 60 litres would be sufficient (for the necessities), especially if your are sharing tent, stove, etc with somebody else...
Also that it would not be so crucial to have everything inside on such a walk.
...and yes, the OT is fairly clear, and not much of a problem for items strapped to the outside of packs.
(and i'm still pondering where smaller doesn't equal lighter)
I'd suggest probably more-so that lighter doesn't necessarily mean dearer! In fact most brands seem to bump the price up with larger packs to start with.
Smaller packs are generally cheaper, I think. Some of the other gear that you might want to put into it may be expensive (if it's not expensive, then it might not be durable or of good quality). When I mentioned cost earlier, I was referring more to my own situation, I guess - Ie, I already own all the gear I need, and can't afford to replace it all with smaller/lighter gear when it all works perfectly well as it is.
As I said in my earlier post, the only reason I really raised the question of a larger pack was to consider what else you may want to do with your pack in the future. A 60 litre would be OK for the OT, but do you ever plan to do any other walks? If so, you need to assess your priorities. For some people a 60 litre pack is fine for a wide variety of walks and helps decrease the weight they carry, and some people prefer a larger capacity for longer walks, or more comforable/enjoyable/luxurious items or easier packing, etc. So you need to assess your own future needs (post-OT) and determine your own priorities. Hopefully there's enough of all perspectives here to give you enough information to make up your mind.
