Damn! I did'nt know that it was disco'd.
I've recently bought one, brand new, that had been sitting in our pro shop for over six months (he couldn't sell it, which is probably why he sold it to me for a "friends" price!).
I find it an excellent ball.
Now I've got them all (Rapid Fire, Rapid Fire pearl and Sure Fire).
I bought the Rapid Fire pearl from the pro shop guy. He had drilled it up for himself, threw 8 games with it, didn't like it and sold it to me for half price!

I've upped my average, so up yours!
