Solas Amita 3 or Rubex 3 Plus

[Valiant Knight]

I am looking for a 3 blade propeller for a Suzuki 90 DF (2006) mounted on a 5.2 m Valiant PT 520, to replace a Solas Rubex 3 (3*13.25*17).
Both the Solas Amita 3 or the Solas Rubex 3 Plus, (3*13.875*19) seem a reasonable option.
Any comments on the pros and cons of the Amita 3 and the Rubex 3 Plus are welcome.
Although I am living in Portugal, I would also appreciate information about where I could buy one of these propellers in the UK.

Thanks

Antonio Carrapatoso
