I am a big fan of the More Cowbell, Goji, SSDD, and, while I haven't done Space Monkey, I love GG4... and I haven't really met a Wifi hybrid that lives up to the hype. It sounds like we have similar tastes.
I would recommend Raspberry Hashplant. It's a little bit more potent than Goji or the other Goji hybrids, but it still brings lots of the Goji goodness.
Of crosses I have not grown, I would consider Secret Chief. Personally, I'm giving Magenta Hashplant a try for a different angle at that power I like. I also have Space Cake and Field Trip going as seedlings, because cookies crosses are usually a sure-shot for that power.
Edit: Soul Mate and Lucky Wookie are my very favorites, but they don't have that crushing power I think you want.
