Touch weight

[madelyn mrykalo]

Fred,
Interestingly enough, in order to get moment smoothly
graduating, we have so far found that a strict leading
pattern will probably get you in or near the ballpark,
but not smoothly graduated.  Just how far we can stray
from a smooth graduation of moment without
compromising the evenness is not yet certain.  But we
did find that once we decided on a front weight
pattern or curve, and made the moment graduated from
that, there emerged a kind of leading pattern, with
small variations.

I hope to have some numbers to share soon, as we have
only just begun to do this kind of figuring.
