Hey guys, I'm looking at swapping helix's in my triumph. It came with a R-32 helix from polaris. In my manual, polaris also sells a R-8 helix. My question is, what is the difference between these two helixes. They are both listed as a 50-34 degree helix. I'm sure one is cut a little different than the other, but how am i supposed to know what the difference is.
