I'm relevantly new to it too. I started with a MVP 2.0 (iTaste) with an Aspire nautilus Mini. Just bought a iTaste 30W and using my Aspire's on that. I've been playign with the settings and I think it all depends on the juice and your set up to find a sweet spot that you like. I'm still messing around with mine. I'm still learning about Ohms and which coils etc so hang in there! This forum is great for info!
