Gunsmithing JCS Composite Stocks?

I haven't run any, but I know a few discerning guys that run them and I have never heard a negative thing about them.
 
That is helpful for sure. Hopefully someone with one in their collection will chime in too. Any idea if they are more or less similar to 'x, y, or z' model of someone elses stock? Im looking to put a new dress on a tikka but the price has me shy with so little information out about them.
