Yep tail protection is a must as are helemts not sure about wrists, you should fall over a fist rather than outstretched hand, years ago I used to tuck half a motorbike back protector dowm me knickers but that probably hurt more than a bare bum. Red do very nice girls shorts with just tail and optional hip removable protection, expensive but so comfy and last years are around half price.
These sound ideal! - the tailbone is the most common injury I always have - apart from alchol induced ones which don't count. I'll have to go find me a pair of them from somewhere!
