You made a good choice.
It's all in the CFM's, you can forget the MPH as a number it's always between 160 and 210.
That's because MPH is merely the end result of squeezing X amount of CFM's through a tube.
The more CFM's you push through the same tube, the higher your MPH will be.
But in and of itself MPH means little, it's in the CFM's.
The more CFM's it can push, the badder the blower.
It's actually the same thing with air compressors, psi's and cfm's.
