I have been running 100k in the front (so it is somewhat spoolish) I normally run 20k or 30k in the rear. I go higher when the traction is higher. Lately the tracks I have been running on haven't been super high bite. The Motonica GP is the first race in quite a while that I ran 42 shore fronts and my car was very very good. The only track that anticipate running 42's or 45's is in Toledo. I always have a few of the ultra-light Ybslow spools with me in case my car gets unpredictable.
