Welcome deadmanish,
I'm also fairly new to the kava scene so I can't give you advice from my own experience. But, from everything I have read I think your best bet would be with the Mo'i or Boroguru strain of kava. With that being said, kava seems to effect everyone a little bit differently. So you're probably best off grabbing a sampler pack from a reputable vendor such as; Global Kava Exports, Gourmet Hawaiian Kava, Bula Kava House to name a few.
