Base rule of thumb for a .40 size engine is to reduce diameter 1 inch when going from 2 blade to 3 blade.

To give better hints... we need to know which engines you are using. Since the TwinStar is designed for twin .25's, which would normally use 9 X 5 props, that means you want to look for a 8X5 3-blade. Closest I know of is a 8X6 by Grish.
