I would love to try the Brain Strain... definately on my hot list. But I did do a taste test not long ago on the Douglah, Moruga and ButchT back to back. Stuffed up my tongue for about two days, but it was interesting to compare them one after the other. I found the ButchT was the hottest by far - but came last in the flavour department (imo). The Douglah was a close second in heat - but got first place in flavour... (imo) and I was not at all impressed with the Moruga. It was tastier than the ButchT but from what everyone was ranting and raving about... it should have been hotter than all of them - and it wasn't (imo). I think effects of pods can vary and are influenced by many factors. At the end of the day, the pod you eat will have about 5 different capsaicinoid in it (dihydrocapsaicin, nordihydrocapsaicin, homodihydrocapsaicin, homocapsaicin and nonivamide). The mix of those four capsaicinoid in that pod on that given day will determine the outcome (I imagine these levels of capsaicinoids fluctuate on a daily, hourly basis). The ButchT I ate that day, felt like a scorpion was stinging me under the tongue and made my ear drums vibrate involentarily. I have never had that kind of pain again, but I am sure that was as a result of one of those capsaicinoids having been dominant... It would be interesting to find out what the physical side effects of each capsaicinoid is...
