Okay so I decided against gettin a block of black walnut to make a new riser. I am instead going to get a pair of riser blocks, out of either superaction, or some type of solid wood. SO my question is what should I get. My limbs are black walnut and maple with black glass. SO I dont know much about wood types, I like gray superaction, but was wondering what you guys thought would go good with those black limbs?
