Looking for a wooden prop for homebuilt. I understand that wood props
have certain advantages over metal and composites. A wood prop has
virtually no memory and is not subject to fatigue as is metal. Also on
contact, a wood prop will not result in as much damage to engine/crank
etc. I know a few guys with Colin Walker props on RV6's and they love
them. Any comment on other manufacturers or your experience with wood
props?

Given all the good stuff you state...
My wooden prop seemed to be a magnet for rain
and took a beating every time the revs were not
held to something below 2100 RPM. In addition,
wood gave no acceptable idle below 900 RPM.
That lead to unacceptable RV-3 brake wear.
Then there is the efficiency factor. SO, fer me...

I'll take METAL --
Especially, for Hamilton Standard, Sensenich,
Hartzell and McCauley constant speed propellers. 8+]
