i see in turks clutching page that he has used both for lake/trail. right now i do not have the cash to buy new 8dn-20's seeing its this close to christmas. so, how are the 89a-10's? i have a WWW primary,green secondary and a advent-edge 48/42 helix. I am not into lake racing ,but i love to smoke my friends on the pond. 80% trail rider. hows the back shift with the 89a-10's? also i thought that the helix had the most effect on upshift/backshift?
