Everybody wants faster. Higher poundage, lighter arrows and broadheads, shorter brace height, you could grow your arms longer and increase draw length.

Seriously, why do you need faster? I' m shooting an older Hoyte at just 58 lbs and have taken 2 deer a year with it, I have no idea what speed I' m even shooting. Skip the " speed Balls" You could go to an overdraw and shoot shorter (lighter) arrows. The carbons I' m shooting are only 7 grains/inch, thats pretty light, but if your bow is set at 70 pounds or somthing you wont get away with somthing that light.
