    For your setup will be a 15/20 SOLAS but you need to check RPM.

    81mm. I have a very similar setup to yours and I gained 1-1.5mph top end (verified w/gps) by switching to the 81mm from the stock 83mm. Holeshot and midrange acceleration did not seem any worse, but I do not have any data to prove this.

    On your setup i would go with a 15/20r and no less than an 82mm ring...yes you will gain more top end with an 81 but trust me you will loose hole shot..NOW if you want to run a 15/19 3 blade then an 81mm ring works well with that combo...
