I find this, too - 'exotic' wire is mostly just different in terms of flavour. Since I mix my juice, I can make any adjustments I care to for profile constituents there.
Interesting that you say you think you chase nic. My sense is that you (we) chase sensation - more a physical satisfaction than a taste thing. When I smoked, I would never have couched satisfaction in terms of flavour (I smoked bland Canadian cigarettes). For me, the flavour fun beyond the sensation with vaping is a bonus, not the main goal. A fun one, granted, and one I happily fiddle with... as long as the sensation is satisfying.
