I've been offered the chance to study BJJ with one of Roger Gracie's clubs here in the UK. It fits right into my schedule, it's affordable etc... But I love doing TKD and don't want to give it up. The classes are on different days but from a previous thread people generally don't think studying two arts is really a good idea. I asked the question about it a few weeks ago. But since then this opportunity has come up. Should I do both or stick with TKD. I'm not giving up TKD so that's not an option. Advice please?
