Ignore all the "experts" and do what you need to do to get better.
If those pocket reducers are helping your game, by all means USE THEM.
I wanted my pockets shimmed up to 4 inches and the installer messed up and only took them to 4 1/4.....(including the sides). When I have it recovered, they're going down to 4 all around....and I'll be watching and supervising.
My table is a brutal training field and not a place for social gatherings.
But, I am very weird and serious about training.
That type of training pays off at match-up time, however.
Have a good one.:thumbup:
