Try the Biela 27-10 for Pattern style flying, and the Menz, BME, or NX 26-10's for 3D. The wooden 26-10's will rev quicker, making 3D easier, and the Biela is a great "Pattern" style prop because it's loading it more consistent. The Mejzlik 26-10 is also a good choice for an all-around prop, but rev's higher than the Biela so it will be noisier when flying, and does not accelerate/brake as well as the wider wooden props in the 26" range.
