Hi
Thought I would add my .02 cents to this topic...
First of all, the so-called true Rico is pin in the palm or grip center, CG at a 45 degree angle from grip center and the extra hole 6 3.4" from the pin through the CG.
Now I can tell you, I have modified this layout...pin shifted so it was 3 3/8" from PAP and everything else at a 45 degree angle on the laterla grip line... moved the pin up the grip line to accomodate a higher vertical axis coordinate...to me a modified Rico type layout would be one that the CG and weight hole is at a 45 degree angle from the pin...
And for the record, a rev leverage layout is one that the pin and CG were 3 3/8" from the PAP below the fingers and the weight hole 3 3/8" from the PAP down the VAL.
