Like manatrader I found doing them( stand ups) on the 600 comfortable. But not on this beast. It's most likely all in my mind, what's left of it anyway. I don't do them alot and when I do it's out playing with the boys. I'll do it passing with plenty of room, big road, and they know it's coming. Don't Like surprises and don't what to surprise someone else. Seen a few close calls that way.
