Papa kea has some effects strong, but I wouldn't describe it as heavy compared to non polynesian varieties. That being said, I've been disappointed by the melo melos I've tried. I think Hawaiian kavas are very good for euphoria, but you go elsewhere for heaviness. I've also drank pounds of "heavy" Fijians, but don't think they're really in the heavy category. I do think Papa Ele Ele has some of the Vanuatuan spaced out effect that I feel sometimes. Ikaika mix from
@Gourmet Hawaiian Kava is quite good for an overall balanced feel. I was on a heavies only kick for over a year, but I am quite over it now. DHM might be okay sometimes while you're drinking it, but it sucks after the first hour and moreso the next day. DHK gives more of a stupid spaced out heaviness to it than DHM, makes your muscles sore the next day if you have too much, but isn't as unpleasant as DHM the day after.
