RE: PROBLEM WITH DRENALIN
Not saying your archery store did this but: Last year a friend of mine got the Switchback XT from a pro shop that I never dealt with, his shooting was just fine until he was shooting over 20 yards, then he was allover the place, he found that they didn't put the bow in the correct bow press, (you need a certain bow press for the new parrell limbs) bending the riser. So maybe that is the problem
