I can say from personal experience that visiting Xtreme Tactics is a fantastic idea. Back when I was thinking about investing in airsoft I went to Winnipeg and shot off some rounds at their range. The folks there are fantastic and will certainly answer any questions you have. You'll try it once and that will be the hook. They also have a locked room with just about every AEG you can think of (NOT FOR SALE). They might just let you have a look at some of them.
