Lou,
I've found that for me, a very forward balanced gun like yours is very conducive to good shooting on most sporting clays and trap presentations. I had a Beretta 12g 682 Gold E with 32" barrels that balanced very forward (I don't recall the balance point and I sold the gun a few weeks ago) and I shot it extremely well. I also have a Browning 525 20g 32" barreled gun that is balanced very forward which I shoot very well at trap or sporting clays.

Don,
A tangent to this discussion that I don't recall coming up is LOP effect on how a gun swing inertia is affected. A lot of shooters favor longer LOPs and say they shoot markedly better with a long LOP for their body size. It seems to me that a 1/2" more LOP is pushing all the mass out another 1/2" and increasing the MOI of the gun to the shooter. That may account, in part, for a shooter "liking" a longer pull in a particular gun.
