I used MG yellows last year all friday and they were fine. But switched to Vega whites for sat and sunday and grip was very similar and those tires lasted 2 additional weekends after MO. Vegas are a pain to mount though. But I was very happy with performance.
Have been practicing on a short track with Bridgestone YNB’s – just don’t have the MG feel. Might bring a set of MG yellows and their harder compound (used to be whites) as a back up. Thanks Jeremy.
