ive played as much on a 5 by 10 as a 4.5 by 9 over the years. and it doesnt make you play better. it fools you into thinking shorter shots are easier. but they are not. same skill sets.
but going back and forth you change all your angles and speed control. so when you change it takes a while to really get fully proficient again. although it may seem long shots are easier.
it is like playing on tight pockets on the same size table. when you go from tight to loose you change how you play position and cheating pockets for position. as well as speed control. and visa versa. it messes you up as you hit the same shots on each table differently. and if you don't you are not playing efficiently.
I played on a wide variety of tables all the time. As long as I did I found big table practice a plus. I have told this story many times but when I was practicing two to four hours a day on a snooker table I had a local small time hustler stay with me a few days. I got to missing my snooker play and took him to the snooker table. With coaching he was making a few balls in less than an hour and doing fair in a couple hours.
Then I took him to an action spot, bar tables. He was first to get on a table. His very first shot he looked up at me and grinned. I said "Yeah." No explanation needed about the snooker table. Action said far more than words!
