Low down on the Rock-Tips. It seems to be nothing more then a heavier based super glue. Not knocking the product but I think you would be better off using super glue price wise. The liquid new skin works as well but its not near as thick as the other two. One thing for sure on the Rock-Tips is they say if you need a second coat to add it. Well let me say this if you do then it will be so cushy that you will not play as good. Just my two cents here is all.
