I've been 122 at Trails on skinnys and a half dead power master and had no problems stopping.
Had I not got the boot for no cage I would have upped the boost... wasn't worried about the shut down at all.
If anything is scary, it would be Larue. Not so much the length of the shutdown, but the pavement. Rough as hell. Been 125 or 126 there on a bike. Fun ride on the shutdown.
