yes i took part in the pre tune up and there were 4 durga and 3 darkimpact.
2 durga were running at 17t BUT the other 2 were not (you can PM me if you want to know more regarding this point). the DI were geared accordingly to their preference and were fast on the straight!
the durgas that were running at 17t were of cos slower than the DI but it has the acceleration at all corners. 17t isn't that bad on a sport tuned in terms of stock class. easy to handle and less likely to crash. oh this bug jumps well!
