RCM pinions are the way to go. they last FOREVER. IMO, they are much much stronger than other brand pinions. here are 2 pics of my older pinions. The first one wore to that from a like new state in about a week. with a fiegao 8L on 5s. The second one is an interesting story. I was jumping my buggy, and tried to correct it in the air. I didnt let off the brakes in time(and my brake endpoint was very high too) and when it hit the ground, the CC2650 kept the pinion almost stopped, while the car rolled, and the spurgear ate through the pinion. Needless to say, thats what happens with non-RCM pinions. Leave the integy pinions for the maxamps racers.
