The distance, takeoff to earliest landing, is written on the takeoff underneath the deck. We measured it the day we finished building it.

I hope, for the sake of racing, that these devices never become compulsory. I'm sure they offer protection, and I'm sure many people will say that they either owe their necks to it, or "would have been saved if only they were wearing one". I don't want to make the morbid leap of saying "Hmm, I might break my neck today riding my bike, let's get the Leatt out". Equally, I don't want to put on a peice of equipment that increases my chances of Clavicle injury more than it decreases the chance of neck injury. There is plenty of evidence that full face helmets and pads prevent injury in downhill MTB crashes. The evidence that Leatt neck braces don't do more damage than they prevent is not yet conclusive, and I should hope that the organisers of competitions base compulsory equipment requirements on evidence and not marketing. Leatt had a very "lucky break" (if you can excuse the unintentional pun) with their introduction to MTB sport, with three or four high profile neck injuries within a very short time. Si, with your position as both a main seller of the products, and as a BC commisarre and as the organiser of the UK's National Points Series, I think it would be wholly inappropriate and a massive conflict of interests for you to decide upon, or even push in one direction the decision on whether these devices are made compulsory in British racing.
