I've been using a Dynathrust 22/10 for the the last 15 yrs. on my cub. Wood and carbon props don't work, they shred in no time!.I don't know if APC make a prop that big(23/8)
I just came back from a week-long float fly here in B.C. and a fellow had a custom privateer with a wood prop that he fastened a strip of copper foil to the leading edge of the prop. The foil was obtained from a place that sells stained glass window supplies. He flew lots and the prop stood up well. I was impressed with it.

Cheers, Dave.
