I have a MFT (two), but also owned two TWH's and now a TWHxMFT. That little guy does nothing but gait
This is what my five year old MFT is rode in:
Seven inch shanks SOUNDS like a lot but in reality it's actually rather short. He carries a snaffle OK but he doesn't like the feel of it when being cued. I put him in a mullen-type bit (virtually portless) and he put his tongue over it and did all sorts of fun gymnastics. Bridle adjusted accordingly, of course.
It's really a nice, quite bit. It doesn't have the nasty square port and my boy really carries it well. He neck reins and leg-cues pretty much anyways, being a greenie we do have to use the reins occasionally but it's quite rare and never, ever, to such a point as to cause serious discomfort. Usually for a little more firm of a cue like "Hey, Red, helloooo Red man. Your falling asleep here, lets turn in a circle....innn a circle. There you go!"
His circles are huge and silly-slow. He's learning to release his hindquarters and loosen up. Lots of finishing work to do when he comes home.
My two TWH's I rode in Hackamores. They where old farts, the first, General Patton, was rode in this OBSCENE 'twh' bit. He was very happy in his hackamore afterwards. Sammy, the second, I think was also rode in one of those mind-numbing-shanks-half-a-mile-long bits, he liked his hackamore (or just a halter, did great in that) and nothing more.
