I sport led my first 5.10 this weekend, and tacked on two 5.9+s as well. While I've trad led 5.9 in the Gunks before, and possibly elsewhere (Pawtuckaway?, Crow Hill?, Acadia? North Conway?, Switzerland? - I can't remember exactly), today was the first day that I've led 5.10 outside. I've led 5.11 inside before (though how clean is still up for debate) and am not afraid of hard 5.10s in the gym
