It looks like the 12X8 or 12X10N could be candidates for trimming down.
Pricy at $37 each!
A BVM remote needle would be a great idea, so you can peak it at a distance on the ground as well as in the air.
IIRC 8-12, 9-10, 10-10 seems to the range of speed props folks have used with success on these .90/.91-ish fan engines. $37 seems like a normal price for a CF prop this size, ILJ estimated the value of CF copies of APC 10" props at about $40 - they're not trivial to make. The trick is not to break one every 5 flights.

Post #33 talks about what some Euro folks are using on their .91's; while they are going for all out speed, the info is useful.
