tpoppa,
I've used Elk Masters & Brunswick Blue Diamond tips for more than 40 years & they have worked great in the area you're talking about, most spin with the least speed & that is what the difference is about. As many say, one can get as much spin with a hard tip as a soft tip but can one do it with the EXACT same speed. It's all about spin to speed ratio.

Yeah, I was going to mention the Brunswick Blue Diamond tip but I didn't think anyone would of known what I was talking about. Boy---when you first put on a new Blue Diamond tip, they are really nice. Now after six months they do harden up though.
I still have a small stash of them put away from lots of years ago.:wink:
