Stocks higher than +50 generally ride like shit, stocks shouldn't have overly high bb's in my opinion, it just doesn't make much sense.
Sure it's great on a mod because mods are practically pogo sticks anyway and are only really good for hopping about on the rear wheel, but now stocks are just becoming like it as well. There should be lower bb stocks so things like taps come back into practice, a lower bb allows for more creative moves and stops everyone from just doing the same moves like sidehops, bring back low bb!
