Actusreus: I have no experience with either product. I've just followed them with great interest. My thinking is that TTWs produced their initial products from copper because they felt it was the better material, although harder to machine. I assume now that copper is not cost effective for them to produce, hence the change. I give TTWs credit for the initial product.
VPI, I assume produced their ring with profit as the overiding factor from the beginning.
IMO.
