In reply to Ciderslider: sol far stats amongst my friends and people I've seen at crags are
Trad = 1 broken leg. and one person with broken pelvis, a bruised spine and 2 broken ribs. so thats 2 injuries. a few avoidable pieces of gears to heads but thats a lack of helmets, not that activity itself.
Bouldering = one broken ankle, one with torn ankle and one with a ruptured bicep. and an indoor severely dislocated ankle.
Soloing = one with 2 fractured ankles off embankment route 3(you know who you are) and one stretchered off with multiple wounds.
Interestingly only the trad climbers could recall their exact errors and stated they were avoidable.
