Thats cause your the best.... and a big reason we all love GG and no other PV will do...
Dual 1.25ohm coil @ 3.7v produces just as much vapor as 7.4v its a little cooler but makes for better flavor and a more pocket friendly GGTS/ODY combo IMO....
I gotta disagree Krinkle. Not even a .9ohm dual coil will put out 1/2 as much vapor as my 2.5ohm 7.4v setup, its just not possible.
Then we will agree to disagree... I run both set ups personally and even with fresh AW IMR pushing 8.4v with a 2.5ohm Ody coil... the biggest difference between HV & LV is what I call drag time... HV requires less drag or pull for large vapor clouds but comes with a much harder TH and diminished flavor... Where as the 0.9ohm Dual Coil is a cooler less harsh TH with better flavor but requires more drag time... I also tend to go with the 0.9ohm Dual Coil method as an alternative to stacking batteries... also note that since that post I have gone from the 1.25ohm dual coil down to the 0.9ohm for a bit more TH... Tastes do change and vaping is subject to individual tastes...
Kir's windows are thicker than the Ody steel body, thus cutting down the juice capacity. Small price to pay for the great look of Kir's clear windows, IMO.
