Agree on the 9"--kinda obsolete if you have a 10" or bigger. I've got a DF and a 1311--I couldn't see the utility of the 9". I'd much rather go 1111 than 911. Part of the reason I never could hold onto the Battle Rat, despite it's awesome dif heat treat.
To each their own, though. I suspect there's a reason the 911 is still for sale
