I like them both and i agree they both have pros and cons. 3 fps....yeah not gonna worry about that. If youve gotta squeeze every last bit of speed out...and it comes down to 3 fps, then something else is wrong. I choose to shoot my deer at 30 yards and under. I shoot heavy 2413 xx75 eastons with 100 grain crimson talons out of a 60# bow thats lucky if it hits 270fps. So 3 fps means nothing to me. Hit a deer with my setup, or another setup that cranks out 330fps at 30 yards...the result is the same "dead deer".
Then again its my money i spend and yours that you spend. I like my limbdriver but i think im gonna trade or sell it. Just my .02
