JJ is probably the most capable builder of the 3 and can do the most fab,,,design wise, depends on how you look at it. I don't claim that Sr and JR's "theme" approach sets the standard for bike building. That part of JJ design is something no one can take away from him and he is on the money. I think Jr and Sr have evolved into theme bike and earlier build were more typical of the simple chopper build. It's kinda like food, everybody likes a different flavor. All 3 are great builders and JJ could probably do the entire bike given the time, Jr second and Sr third. Now Jrs's design are way over the top and if he was capable, which he may be but just not excelling lie JJ, than he could be on top
