Probably just as good as what Tech Spec and others will come up with...the tank grips Tech Spec sells for my Multi are so high up, my knees rarely touch any of it.
How did these work out for you? I dont like the bump texture on those.Since I installed these one of them has had trouble sticking (probably old adhesive). So I ordered these instead. Measurement looks like it should fit the area I need it for. We'll see.
