I have been considering a MA, but there is one circumstance which will make some things tough. Specifically, I have very limited foot flexibility due to birth defects. As they get worse during the day, I have less and less movement, and odd movements can cause debilitating pain. On a good day I have 20% normal vertical movement and less than 5% lateral. Despite this, I have done jobs such as concert security successfully. Except in extreme circumstances I can block out most of the pain mentally.
I am looking for a style that will help my balance and concentration with defense being a secondary consideration. Given my history, I am comfortable in extreme close quarters but prefer to stay away from extensive grappling.
While I have not given much, if any, thought to weapons training, I have been intrigued with the bo-staff. This is an area I would possibly like to explore further.
