You guys are right I'm not going to gain a lot. I was just wanting to be shooting as level as I could be, but I don't plan on getting up to 310 really or nothin close. I just want to do as much as I can within my poundage to get a nice level trajectory. If it's not going to make a huge diff. I'm really not going to worry so much about it, I can shoot it quite well now, grouping 1" @ 20 and 30 yards, and that's good enough for me. I didn't think faster=more accurate, actually the opposite, but hey it'd be more challenging, and btw this isn't my hunting bow so w/e. Anyways, thanks for all the replies.
