JR its a losing battle. No different then the debate on someone trying to replace a DZ and DZ2. They will argue that the blue black and blue green Karma core numbers are too different, the coverstock is too different and they "remember" this and that ect ect.
Just curious, JustRico in your opinion or experience how much difference is there in pk17 pearl and solid, pk18 pearl and solid and pk plus if they are taken to the same surface finish?
