RE: adding speed, or new bow
Not sure, but your draw length is probably shorter than 31.5" If you want to keep shooting with fingers, but want a bow that gives you some performance and speed, I would suggest you look at a Darton Tundra. They are 40" ATA, 7.5" brace, yet shoot at 312 IBO. You will be shooting heavier arrows than that for hunting, but will still get good performance. Mine is set at 61# and 29.5" draw, and it's putting 415 gr. arrows out at 265 fps. If you are on a budget, I would think the PSE Dakota would do all right. They are 41" ATA, 7" brace, and 303 IBO speed, for aroung $250 new.
