The pro shop was in line with what you guys are saying. I am looking at shooting a 29" arrow that is in the 400-425 gr. range including 100-125 grain broadhead. Call me nuts but I like a heavier arrow, but get too much drop and a lack of speed with my old PSE I am shooting.
What kind of speed can you realistically get with a 70lb. bow shooting 350-400 grain arrows these days? Last time I checked my bow I was shooting around 258-260 with 375gr. arrows.
Depending on the bow, you can easily expect 280fps with a 70lb and a 400ish grain arrow. I say you can easily expect that because there are several bows out there that will throw that same 400ish grain arrow 300+ fps. My Hoyt is pushing a 405 grain arrow at 304fps which give me right at 83 foot pounds, which will easily blow thru anything you want to shoot in North America. I don't see the need to shoot a 80-90lb bow unless you are just wanting to prove that you are Heman.
