club sport is a great gym, as is prg. the good things with firstenburg and ballys is they are in vancouver (big plus to those of us north of the river) and the price is much lower. ive only been to ballys once, but we were the only two there, and firstenburg has a monday,wed?, friday night climbs for belay certified only which cuts down on all the kids on the wall.  
but at 5-6 bucks to climb, and short drive? works great for me. 
till the weather clears up at least then its outside only!
