Some people are using Pain - Ningendo while using the Rhino summon. They still use Hinata, Fire Main, and GNW Kankuro. But before then yeah they used Tobi but because of the update using Tobi for lvl 100 exam is just not good. I saw on YouTube that someone was using Scarlet Blaze, GNW Kankuro, Hinata and Shikamaru, the thing was their power lvl was like between 38k and 45k I honestly don't remember.

I was just about to post that video, best part you can be on auto and won't worry about targeting. And if you want to know the exact time to look at the skills, summon, ninjas, and tactics its at 8:05
