Just wondering which you'll get better flight with, quick spin vanes or right helical vane configuration without quick spins. also which would slow the arrow down more?
Quick spins will stabilize your arrows better than any other vane I have tried. They are expensive but work. They are not as durable as some vanes and I don't recomend them for WB rests, but for a shoot through or dropaway they will work great.
I'm sorry, I misread your question initially. I'm with 5-shot. I think the QS's stabilize the arrow better than a standard vane even with a hard right helical, even the 2.25". I'm not sure you will see a huge difference in speed between the two.
