I am from Vegas and bowl there enough (leagues and tournaments) to have some kind of answer for you, but it is honestly my lowest scoring house so my input may not be very valuable.
Okay well, the lanes vary quite a bit every time I bowl there. They actually go from one of the heaviest oiled lanes in Vegas to the most bone dry lanes in the world. However, this may be due to them not oiling often. I have really slow (14-15 mph) ball speed and a lot of revs (? rpm)and usually play the swing shot everywhere I go with a Scout Reactive. But when they actually oil the lanes here, I have to throw an outside line with an Action, so yeah it's pretty darn oily. And like I said before, I don't score very well here, so that's all I can tell you.
Hmmm . . . what else . . . the snack bar isn't bad. Ummm . . . Pro Shop guys are nice . . . Oh yeah, and it's kind of dark on the lanes too, so you can't wear your shades when you bowl if that's your kind of thing.
