Hi Ross,
I encountered that problem with the Stratos 32 a year ago, so ended up looking again and settled on the Gregory Juxt - and I love it. (I looked at the Macpac too.) It carries very comfortably whether lightly loaded or straining under ropes and hardwear. It swallows far more kit than I expected, and has good options as far as pockets, straps and fixings go. It's become my year-round pack for walking, scrambling and mountain-biking.
Minor drawbacks
- the hip-belt pocket is very small (only really good for a couple of small items like keys or spare batteries), but I've fitted a supplementary pouch on the other side of the hipbelt and that works fine.
- the back is very stable but not massively well ventilated, although there is an air channel. It doesn't bother me, I prefer the stability, and having never used any form of 'air-gap' back system I'd say the Juxt is no worse in that respect than all the close-fitting climbing-style packs I've ever used.
- only a single back length. I'm 6' with a reasonably long back (I take size 3 in POD sacs) and I reckon I'm close to the limit for being able to use the Juxt hipbelt properly positioned.
- I don't suppose you can really describe the pack as lightweight, about 1.2kg I think for 28 or 30-ish litres (you can remove the back-plate to save weight but I haven't). But that doesn't bother me, as I said before the comfort, quality and features are excellent.
To me all those points are very minor, i'd say irrelevant to me. The Juxt is brilliant, my favourite daysack for many, many years!
