A bitting expert recommended we look into a Myler 4 eggbutt comfort snaffle for our OTTB who has a sensitive tongue. A few sites I’ve researched seem to indicate this might not be a legal bit for eventing, but I’m wondering if those are outdated.
I checked the Annex 1 guidelines from Dec 2017 (https://www.usef.org/forms-pubs/cd7fgZFu25Y/usef-eventing-annex-1) and it looks like they may now be legal? Bit #25 shows a “Ported barrel” that looks like a ported Myler.
This is my first foray into bit buying (lucky me, I know) so just want to be doubly sure.
