These look and sound really interesting, but it occurs to me to wonder how easy it's going to be to replace a pad on a plastic sax. One of the techniques Stephen Howard mentions in the Hayes manual is bending a key to help seat a pad (one reason why I'll probably never try it at home!). Can ths be done with polycarbonate? Or is there some reason why it won't be necessary? What about other maintenance issues?
Our pad is made of silicone which normally last very long , however replacing those pad is quite easy you will understand it if you see the real one. The pad is self-leveling please don't bend anything it will level itself when it touch the tone hole.
