I've had a VPI table (SSM with Rim Drive), and I have the Boston Mat l (and the mat ll) but have never used them together. I think the Boston graphite mats really augment vinyl playback though. Given the reasonable cost, I would say give it a try. Mat l vs. Mat ll is the question. If you're VTA is adjustable, both will work well. I like the Mat ll personally. It's just more substantial.
