WandC does have some nice leather but as we all know every piece will be different and even different portions of the same side will oil and dye differently.
Personally I would cut the pieces out, case them then slick them real good. This tends to help even them out a bit. You may need to cut a larger piece, wet and slick, then cut out your pattern as this will stretch the leather some but should help even it out. Once this is done I would oil before I did the conditioner. I like to oil, let sit over night, then condition it with lexol or bick4 then let that sit for a few hours then seal it up.
