REFLECTOR: Catto Prop

[Tom]

I currently have a two blade (homemade) prop that is a cruise prop all 
the way. It's approx 63.5 diameter and somewhere in the low to mid 80s 
on pitch. It's really good on speed but is a ground hugger on takeoff. 
At Oshkosh the IO360s seem to use the Catto 66/74 most commonly. Anyone 
have any experience with these? Would really like to improve my ground 
roll especially at heavier weights. Thanks Tom
