I'm switching this year to back tension as well. I've tried the Stan Eagle 4 finger, but I'm not crazy about the trigger being on the middle finger. I've got a Carter Insatiable 2 on the way that hopefully should be at my door tonight. I have looked at the Evolution and while it is nice I would lean more toward the Solution 3 because it can be used as a thumb trigger release. You never know when you might need that trigger while hunting.
