2ndSpace,
no worries mate! :-D
I did not intend to be sarcastic just a bit of my evil sense of humour.
I apologise if it sounded like that, it sincerely wasn't meant to sound annoyed in any way.
I hope we were able to give you some help.
In brief I think whatever you buy should have some decent armour in it and be pretty slide resistant.
Most offs involve either a superman flight and a hard thump when you land (please try to avoid solid objects like trees) and lowsides often result in slides at speed on the bitumen which is why it essential to keep the skin covered.
Onya mate!
