RE: How fast am i shooting?
Honestly, i would go to AT and look for some arrows that would work. I've switched to Axis and bought all of mine there, never paid more than $5/arrow. Most had wraps and blazers for that price. You may have to cut them,although with your length it will be harder to find long enough. Go there, do a search, see what happens. you could even post a "looking for......." thread and maybe get lucky.
Good Luck
