I'm tearing my crownIV down to put new cloth on and new carpet in my "cave". Seems like a good time to ask for some opinions. This table plays tough with 5" pockets. If you touch a rail with any more than pocket speed it hangs. I drew a diagram [not very good but descriptive] of the dimensions of the corner pocket. Standard 5" at the mouth, 4.75 across the middle and 4.5 at the edge. Is this a standard taper for a stock table? I had the rubber switched out from the original superspeeds a few years back and in ignorance never asked about how he would cut the pockets. Wrong or right? Thanks Don
