Hi All,
 
Assuming a Continental TSIO-550 engine, MT Propeller=20 recommends their four blade propeller. 
 
1. & 2.) The climb and cruise performance should be slightly better= =20 with the MT Propeller since each application is a custom designed prope= ller=20 blade.
 
3.) MT Propeller have electric de-ice boots.
 
4.) The four blade MTV-14 propeller and spinner assembly weighs ab= out=20 53 pounds.
The counterweighted blade MTV-14 propeller and spinner assembly weighs=20 about 69 pounds.
(These are estimates based on the weight of a MTV-14 for a Lycomin= g=20 IO-540 engine.)
 
5.) MT Propeller recommends the counterweighted blade configuration.&nb= sp;=20 In the event of oil pressure loss, the propeller blades go to a coarse pitch= =20 setting.  This reduces the propeller drag almost as much as a featherin= g=20 propeller, without the flight hazard of a feathering propeller.
(I'm wearing my flame suit on this one, since I understand a feartherin= g=20 propeller is the current "correct" propeller configuration on this list.)
