Aqua Sport is without a doubt the most well-run and supportive store in Calgary. The couple that own it are avid divers, enthusiastic and offer reasonable prices in a market that is not an easy one to sell gear in (because of internet sales).
I highly recommend you ask at
Mossman :: Deep Technical Diving about this: Greg Mossfeldt is a good guy and straightforward about Calgary's local diving politics, as well as being a world-class technical diver. He will probably back up my advice, though I havent been on his forums for a few years as it's really a scuba forum and I don't scuba.
