Wiaxle, we can't really tell you what to do but if more speed is what you are after. I think the 82, 101, or the Allegiance would all fill the Bill for you nicely. I am shooting a 60# 28" 82 the last couple of days and it is shooting my 326 grain arrow at 308 fps. If you are going to shoot 65# that will pick you up approx. 10 fps or so. Even with your arrows that should still put you in the ball park of what I am shooting. The brace height on the 82 has caused me No ill effects. I am grouping with it every bit as well as I did my Allegiance. The draw is not bad at all. The back wall is good and solid.
I like Speed, but it isn't the end all for me. I am sure my General and Guardian will get time in the Blind and Stand this year

There is no substitue for spending the day at a Range and shooting them to decide what really feels best to you
