FP, Bonds does the drills for barrel control.. His game swings are not any different. His goal is to hit the top of the ball and drive it through his target, but yet knows mistakes happen ( homers ).I am not personally a fan of the chopping action, but if it works for you or anyone else, please continue with it.
In the chopping action that Bonds demonstrates, I get the impression that it is a purposeful movement. However, I do not think that is the case in the game swing. I believe the transition between articulations occurs naturally instead of being forced. That is why check swings are difficult. Your wrists are trying to prevent that transition from occurring, but sometimes cannot overcome the inertia created by the barrel.
