Got the back protector from a local bike shop mate. Cost £99.99. Following on from what Pete said I would make sure it's fitted correctly, and I would say both are as good as each other to be honest. Just make sure that if you get one you go with your jacket. Would be a real bitch if you buy one then realise you can't zip up your jacket with it on afterwards. Knox, Alpinestar, and Forcefield are all good. They are all CE approved, and some of them are CE Level 2 (Currently the highest level of approval). Used the paddock stand today. Makes checking the front tyre a whole lot easier!!! Monkey. Get a back protector mate, they are just as important as a helmet in my eyes. Break your back in the wrong place and it won't matter how protective your helmet is, your brain won't be able to send signals to your arms and legs to make them move!! God I am a right preachy bast*rd about this!!
