That's part of it...they don't fly very well for me.....my Dad has them, and he has problems with them as well....I'm fairly new to this game, so spinning arrows and tuning broadheads is like me explaining how to fix a motor over the web....it's tough...I tried spinning a couple arrows...they don't seem to wobble..but they don't fly straight either...does it matter how much you tighten them? ot which way the blades are facing in relation to the fletch?
