malfred,

using tape both st-30 and walker no shine gave me an incredibly strong bond.. To test it I actually grabbed the hair and gave it a really strong tug. It wasn’t going anywhere.. and I believe it wouldn’t even be pulled off in a fight.. but I also believe you are right in the amount of extra abuse your piece is going to get on the mat. Anyone who has done mat work knows how much friction occurs to your head. Bouncing and grinding on the mat is going to be a lot of abuse on the piece.. but its going to depend on how full out you’re going to be on the mat as opposed to training techniques
