3.7 volts with a 1.5 ohm atty beats 5 or 6 volt vaping any day for me
There are certain things I like at HV and certain things I like at 3.7v w/ LR. I'm really fond of many of my PG or high PG ratio juices at HV, but my VG and high VG ratio juices are mostly used at 3.7v with LR.
Just rolling around my desk right now, there is a VV box set to 4.8v with a standard dual coil - there is a 5.0v regulated mod with a 3.2 ohm single coil carto - there is a Maxi RS @ 6.0v with a 3.2 ohm boge carto - there is a regular RS @ 3.7v with a 1.8 ohm atty - there is a reo mini 3.7v with a 1.8 ohm boge carto - plus a variety of ego and ego clone batts running everything from CE2 MAP tanks to 1.7 ohm Smoke Tech cartos.
I appreciate standard voltage and high voltage for different reasons. One of the things that I enjoy so much about my maxi rough stacks is the variety of voltage choices I have - 3.7, 4.8, 6.0, and 7.4v.
The bolt and an extender have definitely made my "going to buy" list. When I buy one, I might finally feel OK about sending in all of my rough stacks at once for switch upgrades.
