Just got through installing 860HR on my table a couple of days ago, and I am LOVING it!
Great cloth! Have been getting back into straight pool since I can get a decent roll on the table now. It's supposed to be between 860 and 760 in terms of speed, and it seems perfect for an 8' OS table. If I had a 9' table, I probably would have looked at 760 instead since straight pool is kind of where I'm headed...
