Douglas,
Just so I'm clear: when you say you prefer Tongan to Solomon's, you're referring to Tongan by nakamalathome - correct?
Your Tongan Pride by Kava by Rex review would suggest this.

One of my favorite experiences of mixing kavas was soloman island and vanautu3. I put half a cup of soloman with 4 tbsp of van3 to 5 cups of water/milk. So good, hesitant to say one of my favorite experiences with kava
