It seems recommendations and reviews are so rare lately and so valuable with the price of root that I should share some experiences with you guys beyond just my favorite kava right now, so here ya go:
I just got some mahakea in from Chris and only tried it twice but it seems on par with the last batch. These days mahakea for me has been a heady strain above all. It has a little nervous tension from time to time but if taken correctly or blended it isn't an issue. Still i wouldn't recommend it for anxiety or sleep. Has a nice energy to it. Its funny because a year or so ago and previous it was a kava that gave me a mixed bag of alertness and body glow, ssometimes it was weird to me and other times it was spectacular. Now it feels a bit more like moi or kumakua but a bit more balanced and the flavor of this batch is remarkably mild. It tastes "watery" if that makes any sense, lol. Like cucumber without the greenness. Or like a lawena without the nutty/creamy aspect. If you want mild taste or liked last months mahakea then you will like it.
The Nene is par the course for this years harvest, if it isnt in fact identical. Very good situational kava, i use it in the morning for a mild mellow without worrying about side effects. At night in larger doses it leaves me feeling thoughtful and engaged but tranquil. Nene has never been the strongest kava to grace my shell but I can always rely on it for certain results. Also a great kava when you are feeling under the weather.
Hiwa seems stronger than usual. It noted more hypnotic effect and muscle relaxation than with thhe batches from earlier in 2018. It is however slightly more rough on my body than your average hawaiian, but it seems to be proportionate to the body effects that it offers. It's not difficult to tweak dosage or blend to avoid the negative effects. Heavy or not, this is Hawaiian kava, so it isnt going to mess with you like an was-kicking Fijian waka or heavy Vanuatu.
BKH Nambawan is a total powerhouse right now but it is also dizzying and nauseating. I kind of regret buying 2 lbs of it at the premium price because i can only handle tiny amounts. Its definitely nice to have some around for punch but it is like playing with fire at times. Previous batches were a little milder and smoother. This one is very heady and hard hitting.
I also recently received some kava vinaka chiefs choice nad their lawena. The lawena is as good as ever and a good price. Great for sleep and that heady, sleepy feeling. Super smooth on the stomach and relaxes your mind more than muscle relaxing, but that's often what i'm looking right before bed.
The chiefs choice is a quality kava that is super balanced and clean, but past iterations left me more impressed than this batch has. The first couple times I bought chiefs choice it stood out to me as a very unique heady kava that had great social energy and left all my worries somewhere far away. This batch just feels like a plain old, but solid Fijian. If this kava was on sale i might put it in the "must buy" category, but considering the premium price range I will be patiently waiting for a future batch before i pick this up again. The only disappointment is that the bar was high for this one, and with the lawena giving similar strength and effects at almost $20 cheaper per pound, i can't justify it.
Maybe 2 weeks ago i got a small batch of pouni ono and Loa waka from Kalm with kava. The Pouni ono feels pretty much identical to recent batches. Heady and smooth, a bit anxiolytic, good taste, but there is better Tongan out there, albeit for a higher price than Pouni. I would consider this the choice for budget Tongan (If there could be such a thing, amiright?

)
The Loa waka was solid and well worth the price. Balanced and clean, it is so far away from the Loa waka of the good ol' days. This kava used to be a legend. It packed a punch and then faded into bliss. Still though, this is a good buy and good kava.
