I think his idea using oak plywood is to keep the cost down so they are affordable. But I'd agree a nice piece of walnut would look awesome but probably increase the price a bitI like the design, don't care for the type of wood used though. A nice piece of dark walnut would look good.
I checked them out, they are cheaper but those are for skull mounts, they do not have anything like this for european mountsThat's seems kind of over priced for plywood.. Check out Walnut Creek Hardwoods soild oak & walnut for half the price.
