Yes, they look cool especially big tall red ones in the bright sun light. I found to much helical can slow the arrow down. That’s comparing them to parabolic feathers same bow, same fletch jig, etc. at 25 yards. A lower profile does help me get comparable flight with Parabolic fletch. As for noise, if I use my JoJan multi I don’t have noise. I believe my Blitz’s are set with more helical which I can hear especially with the higher profile. Agian your experience may vary. The shape your referring to with the back end trimmed can be had in the “little chopper”. I have one as well along with many others.
