i'm curious to find out as well, looks like this could be a good cheaper tip. i've tried their dynamites and i thought they were really good for the money. i haven't seen any of the resellers selling them yet though. the only thing is i'm not sure i dig the green color
I talked with Tony and Corey for quite a while at the BCA tradeshow, in Vegas, last weekend and they both seem very happy with the Emerald tips. I got a pretty good look but haven't installed one yet. I think people will be pleasantly surprised.
