ok, so im considering a 5v box mod. ive used nothing but a joye 510 so far and i cant deal with the short battery life anymore. ive been vaping 70/30 pg/vg and its fine at 3.7 for the most part but id love to get more flavor and vapor out of it. im happy with the TH at 3.7 with my juices, so im wondering if i switched to 40/60 pg/vg if that would provide a similar TH at 5v. i also want to use less PG because at times its harsh on my throat and leaves me dehydrated. also, would i go through more attys at 5v? thanks guys.
