Just built a new home and have a combo pool/ht room. My room is 12' x 31'. Obviously length wasn't a problem but I was concerned about the width.
I went ahead and got the 8' standard table. WIth a straight-on shot from a side rail, where the cue ball is within 1/3 table width, I have to use a 42 or 48" cue. Other than that, not problems. In my mind, its a small sacrifice to have the bigger table. Plus, my local retailer only carried the 8' in stock so the 7 would have been a special order with lots of extra costs.
FWIW...I went with a Connelly table...very happy with it so far.
