Been using the Kanger Subox for a little over a month now. I'm really enjoying it. Been cranking at 40-45w last few days with the .5 vertical coil. Was at my favorite shop today almost pulled the trigger on a Herkales tank and an iPV4s 120w. Got to thinking for a minute and wanted to get some opinions from you guys. Was wondering if going with the Herkales/iPV4s would really be that BIG of a jump from what I am using now as far as flavor and cloud or maybe even "overkill" for what I'd be using it for. I don't rebuild or drip, with my job and kids I really don't have time. I just want good warmth, flavor, and cloud. If it really wouldn't be that big of a "jump" going to the Herkales/iPV4S as far as flavor and cloud then I'm going to hold off. Any thoughts or input would be greatly appreciated.
