Just picked up a ruleaux 2/3 yesterday evening. Previously owned a tc 100 . I was using the rebuild able de k on the tfv8 @100 watts on the tc100 with some pre built tiger coils from demon killer. While it was a good vape the ramp up was a killer and seemed a bit flat on flavor. Popped the same build on my ruleaux after charging batteries amd started at 100 watts, huge difference. Full flavor not hot at all. Leads me to believe the tc 100 at 100 watts wasn't a true 100 which makes sense to me as it's the very limit of the mods capabilities. Anyway lol, just can't believe how nice it is to fiddle in wattage mode and really taste the difference in flavor of the same juice at different wattage. Only In dual cell mode but with the build I have on seems like 145 watts is the threshold limit for a comfortable tasty vape with my particular build at the moment. Super happy I decided to take the leap to a high wattage mod. Gonna get a set of 3 batteries to run in 3 cell mode and try out a beefier build soon. Oh lord ... from quitting smoking to buying up the whole vape shop lol , I'm in trouble.
