Congrats!
On the blood, sometimes weird things just happen. There's no fool-proof head. That she went 150 yds heart-shot is something too. I still shoot 2 and 3 blade, and couldn't say which has left a better trail for me. My buddy shoots 2-blades and usually gets great blood, but he's also the best tracker I've ever seen. He can track a flea with a limp through a sand storm...well, almost.
Anyhow....congrats again!
