Tough call, but since you asked for suggestions...Have you tried the Bowtech Patriot yet? It might be just what you are looking for. Low recoil/noise level and high speed. The physical mass weight of the bow is roughly equivalent to the Mathews models you mentioned and heavier than the Hoyts. The axle to axle length is roughly equivalent to the Q2 and with a similar brace height..at 34 inches and 7.25 inches respectively.

So far I still prefer the Havoctec to any of the other bows I have tried/owned but its short axle to axle length definitely isn't for everbody.

Good luck with whatever you choose.
