Hey Brad ,
Saw your thread on WED nite racing and thought I would respond here , as you know we have been using this system with great success in our schools for some time now and believe it to be the answer especially for board work . I know Rob Crystal also uses the helmet sets in his school .
On another note we had a complete set go missing from the SS shop in big bay a few months back , if anybody has been offered a 2nd hand set ( in the boxes ) or know of someone that has recently aquired a set please contact me so I can verify the serial numbers that I have on hand .
Regards
Gavin Spowart
