I think any riser wood you buy is getting more expensive all the time…
a couple years ago I loaded up on a bunch of that high density ChromaPly material in 4 colors. The price per riser is pretty good, but getting those 2” thick panels shipped to the west coast was astronomical. I think they are in PA. It’s good stuff. I believe frog blanks was purchasing from Chromaply too. Only they were peddling the lower density stuff, and I didn’t care for it myself…. The HD Chromaply has much thinner laminations, and much better mass weight and strength. Closer to Diamond wood than the cheaper spectra ply .
