The future Mr. Mukluk is 6'2 with long legs and his horse has the mother of all shark fin withers. We were able to find a smith worthington that worked for both. I am 5'7 and have a 32" inseam. I have an ainsley pro national that works for my long femur and fits my OTTB (who does not sport the shark fin look). Good luck and I do hope you will find something. It's such a relief when you do!
