I use the universal charge bar and the powder baffle, and believe the baffle does help with charge consistency. I seem to be always messing around with different loads, requiring different powder charges, and for that the adjustable charge bar is great. If I were to load only one or two recipes, like a sane person would, I'd just use the MEC bar and bushings. That said tho, if I loaded different shot sizes I'd still use the universal since I could tweak it to get the same weight of #4 as of #8.
