I find any borogu quite euphoric but leads to sedation after so no jitters. It's not completely heady, usually quite balanced. Pentecost Pride is a good one for me but KWK borogu is good as well. I've got boroguru from GHK which is apparently the same strain but not tried it yet. Fu'u is pretty heady and I've not noticed much in the way of jitters with that. Usually if I drink a completely heady kava I get a touch of depression after, don't know why.
