you save some weight, but your maint will go up, any time there a temp or humidity change, you need to check the torque on the prop bolts. If the humidity goes up, the prop can absorb moisture and swell, which will cause the bolts to be over torqued, and if it dries, then they are under torqued. It is covered in the Sensenich manual, but it is found in the metal prop manual.

Wooden prop was created by Terrence Cooper
Good morning all. Lil chilly down here in New Orleans today. I have just ordered a Sensenich 72-48 for N93774 w/C85 purely for the reason of beauty. Can anyone blame me?  In the process  of ordering I discovered that the McCauley 73-47 currently installed is not the recommended prop for a C85. Plane has always performed wonderfully with the current prop, just looking for y'all's thoughts switching to wood. Also wood is only 14#. 

thanks, Terry
