Ive still cracked a crank with a toughboy bearing kit, the guy who rebuilt my crank says he sees the same amount of both in his shop, hadn't really decided if the wide bearing is better.
He seemed to favor drilling the case, and running a stock size bearing, and just making sure it gets extra oil.
That said im running two Polaris 800s this year, one wide bearing, one stock bearing, so we will see which one last longer
