I am also in the same predicament, I shot the Allegiance last week just out of curiousity, not even interested in getting a new bow,, Well I loved it and my AR-34 was gone two days later, but now everyone says the Switchback is awesome too, and i have always shot Mathews before me AR. So I found a shop with a Switchback in my dl and weight so tomorrrow Im gonna go shoot the Switchback, and the Allegiance again, I have to OK to bring one or the other home, Im still leaning toward the Allegiance, it just felt better than anything Ive ever held, and it shot great, But I guess Ill see tomorrow, wish me luck.
