Hey JeremyGa, I've not tried Ciscos myself but just got an 2.5 ohm IKV 801 mini with my
50cal. and it brought dripping to a whole new level for me.
Works great with the "Kick" on the 50cal. and on the Provari(with the 510-801 adapter)
@mgb_, for me the adapter just gives that extra layer of protection between the atty and my Provari in case I overdrip. Don't like getting "any" liquid on the Provari connector if I can help it. Never overdripped with the IKV atty though, it seems to hold quite a lot of liquid in it.
