What JohnP says is correct in regards to managing the flare on a full roller.
The only other layout would be the one that has the pin laid out behind the PAP on the negative.
The layout places the pin at 1:30 from the center of the grip at 10 1/8" with the CG on the line from the center of the grip to the PAP. Place the weight hole at 6 3/4" from the center of the grip on the same line.
