Couldn't be a more open question, do you have a price range in mind? A lot of it is personal opinion and feel. Some guys like a smaller bow for weight and mobility, others say a longer bow is harder to aim. Then there is the whole confusion about what system is better. Right now, everyone but Hoyt is pretty much copying the Mathews designs. I am not a big fan of Hoyt's but plenty of people are. If I were to upgrade right now, it would most likely be to a Bowtech, but they are on the pricier side. If money is a limitation, I think the best value in bows are PSE's or a Diamond, which is owned by Bowtech.
