I actually just got back from Youtube!!! LOL Well, all I could find when researching the kayfun was micro coil builds. As I said I've only got the MVP2 for right now, so I'm looking for something that I can use with that, and can coil to the right ohm range. From my understanding, sub-ohm vaping should really only be attempted on a mech mod, which I don't have yet. Money is the damnedest thing! So I guess the question is, will an RSST or a kayfun be feasible on an MVP2? Or should I just hoard my cash and go all out in a month?
Well you are right, an RSST is best used on a mech. Having never had an MVP I really can't speak to that. Yes, money is a hang up when it comes to vaping hardware. There are mechs you can get cheap, my cheapest one was $12, but if you go the mech/RBA route you will need the right batteries, a charger, ohms checker, kanthal, and mesh. That adds up to money, and if money is the problem you might have to wait a while. I think a Kayfun clone might be the way you want to go with the mod you have at present. I know they can be built higher than sub-ohm with silica.
