My Brother I'm aware. I haven't been away that long.MP: not need to buy tape. $12-$15/roll - adds up QUICKLY!
I can tell you as an official on the mat for the whole day. ALL THOSE lightweight mats SUCK to be on all day. The old school heavy resilites are SO MUCH BETTER for the body. I know that doesn't answer your question, but still a fact.
It was like Dollamur mats when they were introduced. I HATED seeing them in a gym as they were like velcro on the top. There was zero sliding on the surface and it you tried sliding, they would rip skin off and/or cause a serious mat burn.
