Well if it is any help, I shoot an 07 Ally, 27 1/2" dl, pulling 62 lbs with a 364 gr arrow at about 275fps. I would assume pulling back 70 lbs would put you over the 280 you are looking for if you are looking for the speed. As much as I like my Bowtech, I agree with TFOX. Shoot what feels good to you. My Ally feels great to me but it doesn't to alot of people. Hope that helps and good luck in your search.
