I imagine it would be similar to The Mask (Sannies Jack x Herijuana). Maybe I got the magical bean, but I've been running the F2 Mask for a couple of years now and absolutely love it. Your typical roller-coaster ride... Souring euphoria comes on smoothly and runs for a bit. Then daddy's genes hit you like a freight train, and make sure you remember what it felt like.
I'd love a KFxHeri in my garden, as I do prefer the high of KF over the Jack. I'm getting ready to pop a ten-pack of Heri that's been on deck for 18 months... who knows, maybe a male will find himself in a dark closet with a KF tramp...
