Dick,
I ditto that 100%. Power alone is not the criterium. Itis the power at which rpm, and the power band needed that is part of your setup decisions.
In my every day experience with pilot friends, this is one very tough piece of knowledge to grasp for the other guy. All those variables that made my head spin when I started out tuning engines, and slowly bye the bye became part of the "natural" feel for the engine at hand. The follow the leader symdrom is what yu see everywhere. Mr. Q- so and so uses this, so THAT is what I am gonna use! Without knowing all the slight differences that play such important roles.
It is he who knows how to combine the few means he has access to, that is the most successful if he has the ability to make do.
