Richard shes seemed pretty comfortable with this so far. Is this bit going to be as clear with directional changes as a snaffle without a roller center?

Richard it is

She's a just turned 5 yr old. APHA- I've always dealt with quarter horses so haven't paid much attention to her lines, but will grab a picture. She's had a decent amount of groundwork. Much more brave and curious than any I've dealt with before. Has yet to spook at anything. Does seem a bit dull, though, in the round pen as far as forward movement. Don't know if any of that info helps

Richard just realized you might miss this without the tag, so wanted to add it in here

This is the other. I'm guessing twisted single-jointed snaffle with shank?
