Nic has a bitter flavor to me that I don't care for. I started vaping and quit smoking at the same time. I've bought way to many flavors trying to find something that I like. For the last couple of weeks it has been all 0 mg or 3 mg nic or both of the same flavor so I can cut it back to 1.5 mg. I've got enough juice on hand that I like or can tolerate that I decided to order some TMAXX's to blend to 1.5 and let steep 2-3 weeks.
I have 2 Smok G150s, a Smok V8 Stick with a Big Baby, and a Smok V8 Baby Stick with a Baby on it. This is how they kind of line up.
The V8 Baby Stick has only airflow control and uses a Baby Beast with a 3ml tank and 510 drip tip on top of a 2000 mah battery. With the restricted airflow provided by the Little Baby even when fully open 6 mg nic can hit a little on the hot and harsh side. With the V8 Baby I recommend pulsing the power button to keep the temp down, along with using 3 mg nic or less. It will produce a cloud of sorts and make a good portable rig to carry in a pinch but isn't a good starter rig or all day mod.
The V8 Stick with the Big Baby Beast with 5ml tank and wide drip tip on it is a better option that the V8 Baby stick. It has a 3000 mah battery. The long and short of this mod is it provides a cooler more consistent hit than the V8 Baby does. It is also capable of producing some fairly impressive clouds while producing decent flavor. Like the V8 Baby stick the only real adjustment you can make is to the airflow. With the Big Baby Beast you can manage a lot more airflow than with the Baby Beast. It makes for a smoother vape with less nic bite and allows a wider range of nic levels. I still prefer 3 ml or less, but it produces a good experience with 6 ml as well. It makes a good night out, or on the go mod if you aren't wanting to carry a box with you. This is not a good starter mod, but probably makes a better for entry level cloud chasing.
The G150 is a 4200 mah enclosed battery mod that can handle voltage as well as temp control vaping. It has a Big Baby beast with wide drip tip. With it you get control over temp, watts, airflow, ohms, type of coil wire used, and a few other things I haven't figured out yet. What I have figured out is that vaping in wattage tends to burn hotter, hit a little harsher, and kill coils quicker. In wattage mode if I run my airflow wide open at at 40 watts, 3 or 4 consecutive 3 to 4 second vapes will start producing burnt cotton. In temp mode using Q2 coils I've messed with it so far from 350f to 600f running 35 to 40 watts. My experience is the lower the watts and temp the lower the flavor and more effort it takes to produce clouds. Right now for really good flavor 38 watts and 600f seams to work very well. It produces effortless big fluffy clouds full of flavor. It seams to me when everything is set right the flavor of the juice overrides the nic flavor to some degree making it less noticeable. It I want to chain vape more than 3 or 4 hits in a row I don't get the burnt cotton that I do in the wattage mode.
I don't know if any of this info helps, but it is just what I've been working on trying to eliminate the nic flavor and provide a decent all around experience for myself.
