Somebody should buy this Fatip Mk1. I'm shocked that it's still available!
I'd buy it in a heartbeat except I already have one. Someone else should jump on it.
The Mk1 is my favorite Fatip. It's not particularly prone to biting you. It is perhaps more efficient than later Fatip models. I use mine at either its design angle (neutral angle) or even steeper.
If there are any available anywhere (new, retail) I can't find 'em.
