I have a Kim Steel table and I put the 860 US Open blue Simonis on it three years ago. I play 5 times a week, mostly an hour at a time, but sometimes, when the kids are out, I can get in longer sessions. There are spots on the table and a few worn (very small) areas. I would think if you had this in a pool room, it would be considered good. How often should you replace the felt? With that in mind, how about the rails? When should you replace those? Thanks.
