masters sit higher on hips/waist, the tm is around the hips, and very very very comfy, but when on spikes or with a saw all day, the tm tends to sag on one side. not to a point that i feel its gonna fall off, but enough to annoy me, my craftsman suspenders held up well in a 4 hour Oak removal last week.
What do you mean by twist?
I have seen guys in master saddles with a stationary tie in point, have saddles turn half way around because their tie in was behind them. A floating bridge lessens if not eliminates this problem.
