shorter axle to axle bows are generally better tree stand bows if thats how you hunt. look into the mathews z7 extreme. shorter ata, quiet, smooth, and the fast speeds you seek. just shoot what is available to you, be it a mathews, hoyt, bowtech, pse, bear, martin, stroether, athens, limbsaver, parker, any newer technology bow will be a huge improvement from your old one by the sounds, there are a ton of good bows out there. try a few and see what you like. (to be fair if i didnt shoot mathews id either be shooting a bowtech destroyer, or a hoyt alphamax)
