The 12X6 is just what i happened to have around the house. The manual says that it can handle a 13X6(so i figure bigger prop, more thrust). Next time i go to my lhs i plan on getting a wood 13X6 just because i think that i would look good with the custom cover job i just finished on my Tiger 60. Are there any brands of prop that i should look for? Any i should Avoid?
I know the OS manuals list some pretty big props but the engines do not always like them very much. My Thunder Tiger 61 could not handle a 13x6 TopFlite wood prop. It worked "ok" with a 13x5 TopFlite and very well with an APC 13x4W. You just have to experiment until you find what YOUR engine and plane like. Luckily these props are fairly inexpensive. I can't imagine experimenting a lot with big props.
