FYI, there are a pair of Nitro swallow-tail "Big-Gun" pow sticks available at Techno-Sport in Calgary on 17th Ave.
They are a few years old (2-3 seasons), one is mint, the other has been demoed a few times but has been ground and structured in the fall. The guy told me ~$450 for the mint one and ~$350 for the demo...sounded like he'd be willing to negotiate.
Also, they are willing to ship gear directly to you if you ask.
If I hadn't just got my new Tanker... the new Nitro may have been coming home with me.
