I'm a big guy (270lb) on 440 Invader. I want a sharp engagement. I do not want smooth and boggy start. Plus, I want strong & responsive changes in the midrange (30-50mph not sure what rpm that would be). I'm not worried about maximum top end on the lakes.
I found the discussion about "lowering engagement on LTD", but it still doesn't answer a basic question: For each change in spring, how much change in rpm engagement. For each change in ramp, how much change in rpm engagement.
It looks like each spring is about 2-300rpm change.
It looks like for each ramp is about 2-300rpm change.
It looks like 1.5g-3.0gram weights are minor (50-100rpm) changes.
And, it seems, each combination has it's own shifting characteristics.
My guess is, my target engagement is around 3800rpm or so, maybe 4000.
Is this a good ballpark for a guy starting out on changes...? Am I on the right track?
