I have a few apvs. My only mechanical mod is a silver bullet I use at 6 volts with a dct tank. I love it. So besides these high end mods like the panzer, nemisis, gsm,which all look great.do they perform that much better? And y? I see you tube videos on them from people like rip trippers and they vapor is amazing! !!is it because he is using a kick in the mod?or are the rbas giving that great performance with just the battery and no kick? ??really want to take the leap and get one. Thanks
