[time-nuts] OP-Amps for 10MHz distribution...?

Just a FYI, some op amps have lower distortion in inverting mode than as 
a follower. This is not intuitively obvious since a follow has maximum 
feedback, which would imply the best linearity. However the distortion 
as a follower is due to the common mode rejection of the op amp. That is 
the inverter has the front end differential pair at a virtual ground 
while the follower moves the differential pair with the signal.
