helpful reply there guf.
If you want to do a surface changes video, I'd do 2 things. One is have a wide range of surfaces, try a very rough surface, like 500, then a middle range such as 1000 or 2000, then 4000 wetsand and then a polished one, like 2k+polish.
The second thing I'd do is film it on a sport shot. On a house shot, I can get most balls to the pocket from the same line regardless of layout and surface prep. A sport shot will show the true differences between surfaces the best.
