Yah I've seen that before. It looks really neat and interesting for sure! I'd love to try one. They only problem is that they seem expensive...

I've got a maze 2 "upgrade" and it ruffly costs the same $42.00. I believe the cost is justified on these blocks as they include a secure four corner mounting system that you will pay 10.00 for on other blocks anyways.

I don't know how the spiral would perform, but it appears to be drilled for the same 4 corner nylon post and spring mounting, could save you some money in the long run (or cost the same as a cheaper copper block and hold down).
