Just my $.02. I have had Bmax drives in a 36 Spectre for over 3 years. I am running significantly more hp than you are and other than the early model propshaft problems (XR's had this too) I have had zero problems with the drives.
If I had to do it again I would go with 6's or Weissman drives, only for piece of mind.
