32-12 or 31-14

[TazmanianDevil]

Got the MVVS 175 and couldn't think about making in more quit and the plane faster.
Now, the engine is turning the 32-12 with 5800-5900 static very quit but not fast enough for me even though on up lines and down line you can hardly see the speed change, much authority.
What do you think ? Is it worth the trial and error ?
Large Dia large pitch or small Dia large pitch ?

Absolutely it's worth it, people can tell you what works for them but it may not be quite what you're looking for. Small diameter, more pitch.
