I have found both Hustlers and Double Kiss on youtube. Double Kiss looks bigger and better. From what I can gather, Hustlers has most tables upstairs and it doesn't really look like a bar as there is no bar just sofas. Never been to either so can't really tell.
My favourite all time pool bar in Thailand is Hustlers in Bangkok (Asok area). Double Kiss looks much more like that than Hustlers in Pattaya from what I can gather from the youtube uploads, so probably I will go with double kiss, its very near my hotel also.
