Mo'i is quite simply the best heady kava I've ever had, and probably my favorite kava. My username is named for it after all It's potent and supremely heady - just one shell of 2-3 tbsp root sends me to giddy, euphoric, everything-is-right-with-the-world land. And the taste is pretty good too. Note that the 1/5 shells for heavy and sedative effects means that they are nearly not present at all - and that's a good thing! This is a perfect daytime kava or a perfect way to get some headiness back after you've had a few shells of a more balanced cultivar and don't want the heaviness to increase. For evening drinking I often mix just a bit of a more balanced cultivar in to round out the effects. And if you're sensitive to heady cultivars, tread lightly with this one. This is the kava I've ordered the most, and will continue to do so for the foreseeable future!
