Thank you all for the responses. Will look into the names mentioned that I don't know.
I should of mentioned that I am coming from a classical seat point of view, and also remedial aspect to fix my body, so my body sits quietly and doesn't interfere with what my beautiful girl tries to do for me.
Is there any instructors around that are very good at looking and fixing rider position, or has anyone had good experience with someone they would recommend? This body is so awkward .
