More helical means more spin....means more control right??

So how severe is the helical arangement of your vanes or feathers??

I just read an article that says shooting broadheads should be done with 8 degree helical and a drop away rest. I also talked with a guy at Muzzy recently about some issues I had with flight last year and the first thing he asked me was if I shot straight vanes or only a slight helical. He said anyone shooting a Muzzy head would get the best performance out of a strong helical vane or feather.


What do you guys shoot and where do I get strong helical setups from??? All I see available at shops is straight and 1 degree.


Thanks
