when I use unregulated mods, especially my reo mini which has such small batteries that have such a fast voltage drain, I add more nicotine to the squeeze bottle than I would vape on regulated/vv mods. That takes care of the throat hit. You can also use a higher VG juice in your reo than you do in your other mods. I make my own juice so having the high nic flavorless juice around is easy. Maybe you could get yourself a bottle and try it? Or just buy higher mg juice for your reo. A lower ohm in your atomizer will allow you to vaporize more juice, thus giving you a more full hit, but it only goes so far for TH. On VV mods you can really crank up the voltage and vaporize more liquid per hit, but when your running off the battery voltage your dependent on low resistance to do this.
