Nah I don't want to spread myself too thin, I'm happier winning the few races that I'm in. I can do a better job by putting in a good effort into less races.
Like at the last event I broke my gearlever in the second last race, I barely had enough time to hunt around the pits to find a spare (thanks Shane Saliba) and fit it; if I had a spare bike that would be much easier and more professional. I guess once a racer always a racer :-)
