I'd have to agree with the posts aforementioned, HOWEVER there's a HUGE difference between a "Master Airscrew" Nylon and K Series props versus the Scimitar (Maple Wood) and "Nylon Grey" (sort of Scimitar shaped) Series Propellers. I'm excluding three and four blade props. In my experience, the Maple Scimitar and the "Nylon Grey" series props from Master Airscrew seem to give just as much performance as the APC props, and the "Nylon Grey" series props are becoming one of my favorites. With that said, I do believe that the wooden props of just about any manufacturer seem to spool up quicker whether its a 2-stroke or 4-stroke engine. APC props are GREAT, but they seem to be heavy and break almost as easy as wooden props. (probably because I'm still learning how to land after about 20 years...LOL)

Just my humble opinion based on past and previous experience.
