Probably not, but I've had such good workings with the 10's that it'd be tough for me to stray unless I had an interest in the Burgers and such.
Which at this time I don't so I'd just go with what's done me well for a long time.
Tough 4 this old perro to change I guess.
And you're right about the 6.5's, I really like a 8.5 in that.
