Ill give you my opinion on bows. You see guys on tv all the time hunting with a 65# recurve. They are shooting like half the speed that most compound bows shoot. Its not about speed or draw weight. Look at the kenetic energy. That's whats important. Granted, speed and weight are how you calculate KE. If your bow fits you, shoot it. Its way more important to have a bow that fits you in draw length and draw weight than to have the fastest bow on the market! The biggest advantage to having a fast bow is it helps on judging yardage, and gives the animals less time to react to the shot.
If you just want to upgrade, great. Youll LOVE some of the new bows. Personally Im not a Mathews fan. My setup is a 2015 Hoyt Nitrum turbo, blacked out. 70#, 28 1/2 draw. Axt Drive 1 pin sight, Axt Titanium Recon rest. I shoot Goldtip 7595 pro arrows, and either Rage broadheads or G5 montec, both are 100 grn. Hope this helps.
