Fozzie,
I will tell you that if you sand your XL to 1500 or 2000 grit (with scotch brite pads), it will tame you ball down alot. If you want a tamer layout, instead of a surface change, I have tried a 5 1/2 x 4 1/2, with the pin 1/2" above the bridge, and the CG kicked slightly towards your PAP, then all you may need is polish. My Silver Diamond is laid out like this.
