I previously trained in Wing Chun (had to give it up for financial reasons) and I loved it. I found it a simple-yet-complex martial art and certainly a very thought-provoking one.
Good luck with your forthcoming sash test and here's hoping you continue to enjoy your training for many years to come.
Welcome to the boards. I, too, amd new here but it seems an excellent place for all you MA requirements. I see you are also in the UK. You study anything else as well as WC?
