The way we should look at it is that we are playing a sport with all the relevant safety measures, we all as players have a choice to or not to wear a helmet and another choice whether to have a stem/neck guard. It should the choice of the player alone. With regards to the devices that I've seen the Masuri Stem Guard is superior to all others (I've been using one for over a year). You can't feel the Stem Guard all you hear is a small clunking when you run but its easy to get used to. I've personally never been sledged for wearing a stem guard but this could be due to playing Prem and Div 1 standard where you do come across the odd ex international or current county player. I feel that as an amateur player that is playing for the enjoyment of the sport that its a good thing as I'm not being paid so take that element of risk out of the equation, in fact its helped me playing the short ball as I trust that if I misjudge the delivery then I'm wearing the best protective piece on the market.
