Honestly 2 amp charging is nice but I think the best upgrade is the removal of the old "reverse protection" aka the plastic ringsI would second that. The Triade 250 has reverse polarity protection on the board (the 200 doesn't) and 2A charging if you charge in the mod. And yes, 50W higher rating, but no idea when you would ever get that high. The Wismec DNA uses the same chassis and 510 connector as on the RX200/S, which is fine on a $40 mod, but not what I would choose for a >$100 DNA mod.
