Short answer to the question is NO. Speed's got nothing to do with it. I've never had a pin set for under 20 yards on any bow of mine, dating all the way back to the days of steel cables and wheel hangar brackets, when 210 fps was smokin'.

Actually, except for special tuning and testingpurposes,I quit using sights altogether about five years ago. Never used sights on myhunting bows anyway.
