I really loved their Hiwa and Opihikao (Spotted Hiwa) and Hanakapi'ai when I drank their fresh frozen root a couple years ago.
I definitely enjoyed the Panaewa and the Nene, may have tried a Mahakea, overall Hiwa is one of my favorite Hawaiian cultivars regardless of fresh frozen or not, but the fresh frozen is a very special treat and my friend has been talking about it ever since. It's basically the only kava he enjoys the taste of.
One time I asked for as much Hiwa as possible and got like nine pounds of straight Hiwa from Pu'o Hoku Ranch.
I have eaten their venison (Sweet feed Hawaiian deer) and apple-bananas, honey, gotten a bumble-bee tea towel from them...The price doesn't always fit in my budget, however when it does, it's worthwhile for the experience of fresh green kava.
Oh yeah, I tried an Isa from them, too. I don't know if I had to ask for it, or if it was a random inclusion, it was certainly unique. Sticky, piney, yellow-gold brew color. Seemed to have digestive benefits but did not do for me what regular kava does. Glad I tried it so that I know what Isa is!!
Definitely check out the Hiwa if you get a chance!!
