Thanks guys, it's lovely in here, very helpful!!!
I went out today and picked up an RDA, didn't have much choice as my RBA ISub G had sprung a leak and was costing me more in lost juice than the price of a new unit! I got my hands on a Sapor, top vent, twin coil, and i'm loving it, not like McDonalds loving it, like LOVING IT!!! Thoughts??? ;0)
