Bomber bit advice

[Debsflo1]

My mare 16.1 ISH is currently in a happy tongue loose ring bomber.
Prior to this tried lots of bits and seems to prefer the port and no joint.
I've started doing more schooling work and having regular lessons to ensure we are moving forward and now she has started evading the contact by throwing her head.
Instructor says we are progressing
I realise the importance of schooling and small steps plus ,saddle ,teeth ,bodywork etc and bizzarley she is in the best place healthwise for a long time.
I'm considering swapping to a hanging cheek or the dc Morgan.to see if this helps, been in same bit for 3 years
She gets her tongue over the bit with jointed bits so wondered if anyone has any thoughts on which to trial first in addition to our schooling to make her more comfortable.
I am considering a bit fitter as well if I can't sort.
Shes also in a micklem and works better on a long contact and is big and long with a tenancy to be on the forehand.
Thoughts please

Have you had her teeth checked recently in case she’s developed some sharp edges?
I changed from the Bomber Happy Tongue to the Bomber Ported barrel and it’s working well. My horse also tended to get his tongue over the bit but not with this one.
you can have them on trial from the bit bank. It’s very reasonable for a months trial.

Yes teeth checked.
May need to trial one and see

I've happily used the Bomber happy tongue loose ring like you do.
However, I just had a niggle I needed to work through and a friend suggested I try her Bomber loose ring elliptical B bit, I poo poo'd the idea as B hasn't previously been happy in any jointed bit (and I've tried a damned good number 12 to 18 months ago) B also had developed the knack of tongue flipping in anything she didnt like, particularly jointed or Mullen mouth bits.

Long story short, she posted bit, I grudgingly tried it and wow, amazing difference within a short while, complete game changer. No drop or grackle needed, just hunter noseband.
I now hack using the happy tongue loose ring but jump and school in the Elliptical B bit, so I feel we are currently 'sorted'. This one

Def worth getting a 2nd opinion and looking outside the box x
