im debating the provari versus the darwin as well. so far ive seen things i like about both but ive also seen things i dont like about both.
the first video i watched about the provari....i thought it was a joke video. Saturday Night Live would have had a field day with that video lol. "just press this button 57 times to change your voltage...its THAT EASY!"
the arm on the darwin is a problem, but i doubt id toss a pv with a tank on it in my pocket anyway even if i did have a provari. just seems like an accident waiting to happen. there are other potential problems i see as well: the button looks too hard to press and the wheel looks too easy to move. and the fact that you cant swap in a fresh batt for the d'win when your on the go.
however, the darwin would win in a battery contest if you forgot to have a charged spare battery for the provari. if you forget to charge the darwin, you can use it as a passthrough (assuming your near a power source). so i guess theres no "real" winner there.
are there any other mods out there that will tell you your atty/carto resistance?
