I'm having a bit of trouble understanding the load lifters. Based on the pack fit articles on REI.com, Osprey's website and others, the load lifters are supposed to be at a 45deg angle coming down to your shoulders. However, I'm trying to find a good weekend pack and none of the ones I've tested have been even close to that. In fact, I've realized that the load lifter angle is essentially based on the pack's distance from the hip belt to the lifter's attachment point on the pack - it needs to be your hip distance to the top of your shoulders plus about 2". Even on a pack with an adjustable suspension, that distance isn't going to change since the load lifters are sewed on, so I can't change it.
So far I've tried several packs (Osprey's Atmos 50, Kestrel 58 and Talon 44; Granite Gear Leopard 46; and the REI Flash 50) and none seem to be fitting correctly according to the pack fitting info.
Also, I can get what looks like a good fit in the mirror on several of them when I have the shoulder straps tight, but as soon as I let a little bit of the shoulder strap tension off to put more weight on my hips, the packs seem to tip backwards, rather than dropping down vertically onto the hip belt.
Any suggestions and information is greatly appreciated.
(PS. I'm loading all these packs with approximately 30 lbs of my normal gear so I'm comparing apples to apples...)
