From what I discovered first-hand, you definately need some serious head oil if you plan on using the Second Dimension at 2000 abralon. I threw about five shots with mine in practice one night and it was just too much, too early. I had to throw some polish on top of it by hand to get it through the heads. Turns out that's a great surface for me. I've kept my Second Dimesion at that 2000 abralon underlying grit with just a coat of polish applied by hand since then.
