I bought a 900 Global Wisdom because I don't know much about bowling and believed their hype. It worked great after I got used to it. After about 50 games, the pro shop polished it and took it back to the out-of-the-box finish. I lost about 30 pins. Now, after about 100 games, it works like it did before and the 30 pins are back so, yes, I think the surface can get better for you. I don't know why that would be so but I won't let them polish my ball again.
