Ali- not to say it wont work great, the ION (after my mods which made it much more "friendly") was a nice pack. I just found the top closure to be a hassle. In stock mode, I just thought something else would fit the bill. If it works for you, wonderful! I also will be the second to chime in about the 3200cuin/weekend and say its (the conduit) is much too large for my 3 season overnighters. But. The conduit is the best fit ive ever had on. Like David, it seems the conduit was made for me. If I could have only one pack, like the OP is trying to find, it certainly would be neither the conduit or the ION. Maybe the perfect pack doesnt exist, thats why we all have at least 2 of 'em. (i have four :) )
one of them is a custom Blast 1600. water pockets and an outside pocket. cuben. 3.9oz with waistbelt. ask Joe Valesko to make one.. mine was $60
