The 4.5" pockets are brutally unforgiving. I would not recommend unless you are a very good player and want to really challenge yourself.Great point. Does it matter more on a 7ft table? I was leaning toward the 4.5" because of the smaller table, but I didn't think about the bevels, etc.
I've played a lot on a 7' diamond with the 5" pockets and it a lot more fun.
