RE: Importance of speed?
I ended my archery season over a month ago and haven't shot until this past weekend. Pulled my Allegiance out and after about 20 warm-up shots from 20 yds to 35was drilling a cup dead center at 65 yds with it on the first shot at that range and the other5 hit within 2 inches of the cup.At 91 yds drilled the vitals of a bull elk 3-D target. Would I ever take shots like that on animals, no. However ,just giving my experience with my fat bow.
I shoot all sorts of angled and body contorted shots and still shoot accurately and I know my form isn't perfect every time. I never did that with any bow I used in the past at that range.I use a short arrow (27.25" w/ a 30"DL)that weighs around 400 grains @ 72 lbs (284 fps). According tosome peoplethat should be a very unforgiving set-up and I had a4 yr layoff from archery. The bow is amazingly forgiving.
If you can shoot it accurately the more speed the better. You'll have increased momentum with the same arrow weight over someone that shoots a slowerbow and if you hit bone you'll be better off.
