Sorry about that last post, working on how to get the "quote feature" to work. I meant to copy..."I shoot 28"s at 60 lbs , a 28 inch 400 spine beman matrix shaft , around 400 grains with 5" feathers and a 100 grain muzzy ." and say, "WHAT A GREAT SET UP! I love those shafts. Have 2 dozen 400s and 2 dozen 340s in my garage, since they are discontinued. ..As I posted before, I had NO problems with my allegiance, until I changed the string. I now have it tweaked back to the original length and things are much better. It took some work. THis is a great bow. I love the back wall. I actually am a big fan of the bowtech duallys, having owned patriot and pro 40 duallys. I had a custom type of dually made up that shoots like crazy. It isthe best shooting bow that I have put my hands o. It is an allegiance with bkII cams. It has a super solid back wall and really shoots nice. The ata comes out to be longer than the allegiance with binary cams.....
