Yeah I have the TM Warthog and the Saitek pedals are in the mail.
From what it seem jaw on pedals are the best option. Right now I'm using jaw into role and its really annoying. But i need jaw and with no pedals i don't see where to put it.
I don't have pedals so I just use the toggle function to switch between Yaw and Roll on the X-axis. By default, it's on yaw. When I hold in a button, it goes to roll. I've never needed to roll and yaw at the same time so it works out and feels very natural. But again, it's up to everyone to find out what works best for them.
