I asked a similar question a few weeks ago regarding the Zinger pro in comparison to other (more costly) props. Apparently, NO ONE has strong opinions about the Zinger Pros. I've been using them for about 4 months, and they work fine for me for aerobatics and some limited 3D. (My plane is tremendously overpowered, so the type of prop doesn't matter much.) I even had plenty of power using a plain Zinger.

In general, the wood props are light-weight, and spool up quickly.
