Well the thread you posted (which i have read before) basically slated all bits apart from snaffles, but werent different bits made to suit different horses and their needs. Surely not all horses go best in a snaffle because of their build, mentaility, training and how fleshy their mouth is.
And as i already said, i am currently getting lessons from a very good and accredited instructor who is helping me with my riding in general, but whilst i can have my mare going nicely in a snaffle during flatwork, she is a VERY fizzy and forward going horse naturally, she is NOT going to change, everyone who has seen her and taught me has said that, but im just trying to find a bit which is not going to put pressure on her poll (i am not trying to resort to stronger bits as i have seen my error in her being poll sore) but i do need to be able to control her speed wise.
Its not fair to jump to conclusions that my horse is not well trained as i jump and hack her in a gag, I am asking for constructive advice rather than people slating the way i ride and care for my horse thank you!
So if you do have any helpful advice, about any bits you would suggest i would love to hear them but please no more criticism!
