You know, it's not exactly set it and forget it as most say, depending on your atomizing device. I've found that with any atomizing device I've used, the older it gets, the difference the vape tastes. You may have to raise or lower the voltage/wattage to maintain the same vape experience, until the atomizing device either gives out or needs a cleaning or what not, then you have to start over. I've tried many devices, but find that I keep going back to carto tanks. Price wise, it's really not that much difference than other devices. Unless you're rebuilding coils. But to me, that goes along the same lines as making your own juice, and I don't do that either. So yes, while joe schmo may rebuild his attys and make his own juice and have a much cheaper vaping experience than me, that's just not what I want to do. I did RYO with loose tobacco and empty tubes when taxes went up and I didn't want to pay so much extra. Did I like it, sure, it was fun. Would I have rather have paid the extra to not have the hassle? Hell yes
So yeah, now that I've gone WAY off what I was trying to get to, what it boils down to is, everybody's experience will be different. The guy at the vape store today when I bought my V3 said that he thinks AVG and RMS is just a load of you know what, and you shouldn't need to change the VAMO from Num1. He said some people thought Num 1 was for single batteries, and Num 2 was for running stacked, and he lets them think that because to him there's no difference. When I tried to explain, he said it's just a bunch of nonsense. So yeah. Use what works for you.
