Here's a question for everyone.

I just received a 20B Rotary from Bruce Turrentine to put in my BD4 which I currently fly with a Ford V6. Now, I need to build an engine mount for the 20B but I can't decide whether to use the s-beam mount or the flat plate mount like Tracy uses. They both have advantaged, but my question is, in a worst case scenario, like if I should through a prop blade, which of the two mounts mentioned above will keep the engine connected to the plane longer? Or are there other alternatives that might be better?

I would love to hear any and all opinions on this subject.

 I would (will) go with the flat plate. All of the pan bolts are involved. Four Lord style mounts involved.

Compact and uses the engine block for added stiffness. I will include the nose gear in my mount to reduce fire wall complexity. Possible oil control benefit.
