Resistance in the mouth - Is it always the bit?

Have you looked at the Myler barrel mouth pieces and the bombers happy tongue? These tend to avoid tongue pressure i believe.

Have a look at the acavello 'sensitive' as it's very fixed and still. I picked mine up 2/3rd hand. They do another one that looks intersting with loose rings, too.

I think this is similar to the Beris soft bar bit which I have - and she has chewed?
I am currently borrowing a peewee and it’s lessened her resistance and I use minimal rein contact. If this works longer term I plan to transition to a expert comfy barrel.
I think weakness is playing a part so we will set off on lots more of hacking and polework this winter
