silver lace roo to buff lace hen

the reason I'm asking is a friend of mine lost all of her champion buff lace polish roos and I'm trying to help her out you see I have one of her line of buffs a hen and wondering if I should bring it to my silver lace roos witch has the best lacing I would bring it to my golden lace but the lacing is smutty in the wing but my silver lace does not have the smutty in the wings. I have not don this cross be for. I do not have a buff roo but if you take a golden lace to a buff lace all the offspring are buffs. any thoughts

that should result in buff roosters? if my guess is correct. Buff is consdered gold right? so silver over gold would make a reverse sex link. So all hens would be silver and all cocks would be gold.
