twist hard, go fast, simple as
from reading and listening to lots of this, the difference at the speeds we travel isn't huge. Yes there will always be a difference, as long as its 1 or 2 hp, and I lose no midrange, thats fine. When you start talking 180 hp, 1 or 2 for ours can be 10 or 20 - so worth the investment and time.
Aim is simple; good strong wide range, good fat torq and 63 hp flat balls out...and dont brake!
