Acyually we can not answer that question because we have no idea of how big your hands are. The only answer is use what feels comfortable in your hands and tell everyone else to go someplace.
Actually I can answer the question without knowing how big his hands are.
Don't do XCM. It's not entertaining, it's not magical, it's just boring. No lay audience will enjoy it for more than 1 minute. Need I quote Dai Vernon on this?
Hold back on the scripture!
XCM or flourishing isn't really a performance art, it's just a little hobby that's fun to practise. I do mentalism and some bizzare type magic so using flourishing would be completely out of place (just got the vision of a mentalist picking up some tarot cards and doing a sybil) but I still seriously enjoy picking up the boards every once in a while and working on my Madonna.
