Paul,
I do not have the prop you are looking for but have used a wood Master Airscrew 12x6 for years with my Stalker pulling a 62 ounce SV-11 with good results.  Always good to have options.
John

   In your location, you should not have any problems getting Xoar props. I like their 13-6 and 13-5 for my ST. 60's. They work better that the venerable and unobtainable Rev-Up 13-6.
   Type at you later,
