I want to set up a grappling mat and have researched over the internet and have found many different ideas and alternatives to just buying normal mats. The most interesting and cost effective idea seems to be using carpet inlay covered by a tarp. You can get high density ones and build it up to as thick as you want. Now I'm pretty sure this will be more than fine for rolling, drills, ground etc. But I'm wondering how it would be for takedowns and throws. I could make then 2" or 3" high if needed. Has anybody used or trained on a set up like that? Thanks. P.S. I wasn't sure if that belonged in the G&E section or here, but please feel free to move.
