Has anyone adjusted the stock fit on a 20 ga Legacy beyond using the included adjusting shims (B-C-D)?

For an average sized guy, (5-11, 165 lbs, high cheek bone, slim build), the factory's "C" shim configuration works fairly well for skeet, but the stock contact is high on the shoulder. javascript:void(0)

In order to fine tune the fit, I'm considering using an "A" shim to reduce the comb angle & better place the stock under my cheek and add an adjustable recoil pad to lower the point-of-contact on my shoulder. javascript:void(0)

Comments are welcome from anyone with experience along these lines. javascript:void(0)
