i started off with ego-t and with a smoktech tank and a booge carto and it was good... then i went vv witha vmax with my smoktech tanks and standard resistance cartos and that was better... then i went to a aga-t rebuildable on my vmax and i am damn impressed so much flavor and so much smoke production. my l-rider lambo gives me a nice smooth hit on my smoktechs tanks with cartos. ive tried a bunch of other pv with carto tanks systems but my vmax with my aga-t seems to do it for me =D i do believe the best throat hit and smoke production comes from atomizers but thats kinda my personal prefrence you might want to look into atomizers thats if you dont mind dripping but there atomizer tanks as well im just rambling hopefully this helps a little bit
