I did use the endurance races this year as great practice time on the track in a race enviroment beings that I had not ever been to any of the tracks before but enjoyed the sprint races more (probably because I smoke and can't seem to find time to go to the gym and prepare myself for endurance races) but I will say that I would still pay an extra 10 or 20 bucks to do this. On a separate note, possibly opening up other classes to racers by broadening engine restrictions etc may get more people signing up for more races. I would race ST GTU next year as an additional race if I can ride my 848 in that class
