Matt is still working on it. He will be using a couple of new ones tomorrow. Looking forward to what he comes up with. I'll post when he let's me know something. I haven't used the pucks, but every time I"ve heard any iso gear, it was great for the money and honestly, just good no matter what. I know a very high end dealer in the south who sells some very expensive footers and shelves and he loves the iso a TON. Not everyone wants to or needs to spend thousands on platforms or footers, so the Iso stuff is a great value as you aren't sacrificing anything. I also have never heard the HRS stuff not sound GREAT. Their footers aren't too expensive based on the cost of others footers and he has them to play with. That is the one I'm waiting to hear about along with Symposium rollers.
