I have experience with only one brown marble and I own a 30th anniversary grey marble (first run)...I'd have to say that the new tables with the aluminum siding (assuming that is what the F5 is) play more comparably to the recent grey marble. I think my grey marble plays fast but the later models grey marbles with the new surfaces played more slow and controlling. Someone in our area just bought an F5 from the US Open and I have to say that it is a very nice table and plays awesome. The F5 "feels" much better than mine at home and the control is as good if not better. If you're buying used, make sure you find out if it has the new bearings. These were fixed during the last run and were at the US Open. You'll know if they are not the new bearings if the ball will easily pass through the 3bar men when pinned against the wall. They had these tables at the MI states, and in order to catch a hard wall pass, I had to pull on the 3bar. Not fun!
