They are the same stuff that physios use as resistance bands. I have just replaced my 'power bands' on my Saunders wrist-rocket pro with with some cut from TheraBand Gold. I have never used surgical tubing but my understanding the main advantage is speed and the fact that you can stack them e.g. mine is a double band.
