I had not considered flashlights for the illumination advantage (versus just weight out front). This will be interesting... Worth buying a new holster, probably not.
I, for one, will likely put a mag pouch out front just to see if I like it. Maybe it sticks, maybe not. Aside from stand and shoot classifiers, I don’t think it matters.
In my area, mags on barrel stages are somewhat frequent, so the magnet is appealing, but not really a game changer.
Re-reading my post, I think the sentiment is clear. These rule changes are a distraction and are not going to change who does well at matches.
