***you must first have something that will stop the shoulders. A side net will do this***

Vaughan, safety is priority so don't take this the wrong way. Where did you find the data to back up your above statement, "a side net will do this". IMHJ, you way over estimate the capabilities of a right hand side net.

I'll take my Ultra Shield Pro road race seat, six point harness with a Defnder long before I'll skip the Defnder & use a right hand side net.

***So you need good tight belts,***

I would like to believe this ^ is normal process for all racers.
