It all depends on what your goal is.
Help the individual pro who's shooting best? Or help grow the game of bonus ball so it becomes a success in general, maybe gets on TV?
If the first one is your goal, then yes, bigger tables or tighter pockets help whoever shoots the straightest that day.
But if you want to make a fast-paced exciting game that the public enjoys watching, leave the table alone. Seeing pros miss doesn't do anything for the spectator.
A common bonus ball criticism is that it's a completely different game that the general public can't relate to. But if someone likes BB and wants to try it at their local pool room, they can 'fake it' using stripes and solids and maybe a shotclock app built into their phone.
But if you move it to a ten foot table you have a game nobody knows, using balls nobody has, on a table you can't find anywhere.
Personally, I hate that the pool world is already fractured between barbox play and 9-footers. There's an 8-foot size that gets largely ignored as well. We don't need to add a fourth size to the mix by trying to make the 10-foot gimmick table a new standard for all pro-level play.
