T3S/MT3S heads can be used in any Kanger BCC tank, PT/PT2/Mini PT/Mini PT2. With the T3S base, can be used in older T3 tanks. Protank and Evod heads, can not be used in a T3/T3S tank system. Only difference in the three types of heads, the T3S head in narrower by a couple micro-meters at the bottom flange of the head that seats flush on the base. So yes, it is compatable with the Protanks. Regarding the flavor wicks, if you getting dry burns, remove one wick, test it out, still getting dry burns, remove the next one, depending on the viscocity of your liquid (PG/VG ratio, higher VG will need flavor wicks removed).
