Dufour 32 propeller

Hi,
I need a new propeller for my Dufour 32 Integral, eqipped with Penta MD2020 /19hp.
Looking for a 2 blade folding prop. Do you have any recommendations, esp. in size?
I have been offered 15x9 and 15x10, tending to 15x10. Do you have any experience?

Actual propeller was a Variprofile VP64 3-blade 15x12 which hardly survived 13years in the muddy wadden sea.

Thank you, Swen-Olaf
