Yes, I'm reviving this thread.
After carrying my KU 3700 religiously this whole season, I can honestly say...
I LOVE IT!!!
But not without some wishful thinking?
#1 I wish it had a bottom zipper for access when it's full.
#2 I wish it had a row of pals (similar to the Timberline/Legacy packs) on the sides, or tabs (similar to the High Camp) to hang pouches from. I think tabs would be ideal to save on weight?
#3 I wish it would attach to a Duplex/Bikini duplex frame as a bag (sans belt, straps & stays).
#4 I wish it had a longer carry loop.
Why mess with it you ask?
I found myself constantly grousing every time I had to "dig" something out of the bottom.
Also, I have not found a good way to hang anything to the current bottom pocket holder.
A buddy of mine has a G2 Duplex hauler, and after some testing... We could not make it work well at all. It definitely was not a good idea?
When picking it up with moderate loads, the carry loop is just too short.
Other then that, it is the most comfortable pack I have ever owned! Even with my "wishes" I will not trade it for anything... The weight, comfort & durability trump my perceived shortcomings in the pack. After a full season, the pack is dirty. That's it. Durability has not been an issue for me. I hope Patrick and Aron continue to improve the KU's right along with the Legacy packs and the addition of the High Camp/Bikini duplex combo.
