I've never been able to use him because the only bravery mares I own are EEEs. I could breed one of my non brave gals to him but the bravery rating is gonna suck.
I pulled an embryo from him but the mare wasn't one of my braves. He is lovely though. I still have straws from my WWW-E TB boy. Maybe I'll catch something for him during the next capture event as I'm swimming in maps!
