  This has been kicked around on the Exploder before, but I've slept since then.  
I'm considering swapping out the 2-blade Hartzell on my S2-B with a 3-blade 
MT.  I've heard that it will increase low speed pull (e.g., better 
accelerations off the top, etc.), but that it may take a few knots off of 
cruise speed.  Fact or fiction?  Is there a substantial difference in the way 
it will snap or hammer due to lower gyroscopic forces?  Are there any AD's 
against the MT?  Any other observations?
