As a guy who uses Konoha blitz (Danzo-Iruka-Asuma ~72k) these are the following teams that give me trouble at similar BP:
1. Shield teams, mainly with earth main and a well timed Gakido
2. Kimimaro teams with water poison tai - Kimi being positioned in the middle row and the other ninjas "lower"
3. Wind mains - with blind passive or dust
4. Blitz with higher init P1

Points 2,3,4 can be countered by blitz with Iruka, Danzo or waiting in case of blind and a little luck.
At similar BP, Sage Naruto and/or Roshi are not viable, they die first round.
