I know exactly what you mean lol.
We got the halo sampler, and I made a lucky semi-educated stab in the dark and got a 30 ml of T56 with it. I couldn't stand any of them in the sampler, and the prime 15 tasted like a huge cigar to me.
T56 has a slightly sweet taste to me, but only slightly, and a GREAT TH and vapor production - and it reminds me a ton of a huge drag off an analogue - which is exactly how I smoked them. I ran out of T56 and was stuck on prime 15 for three days, and was miserable - a noob mistake that I'll definitely learn from lol.
