Snausages

I recently acquired a pair of Snell E3's which a Snell engineer told me have an RMS rating of 150 at 8 Ohms.
I want to get a receiver that can power them properly and have been focusing on a few Onkyo models for a variety of reasons and features they offer that I would use.
My question is how to determine the proper power to put into these speakers and whether I should Bi-amp them.
The Onkyo TX-RS750 and TX-RS850 both support configuration for bi-amping speakers.
The 750 is outputting 100 watts per channel. So I assume that if I bi-amp even though two channels would be each sending 100 watts into the speaker I don't actually count that as 200. I would think that rating would be a bit low. I know Crutchfield recommends at least 70% of the RMS rating provided (which is 105... I'd be just a bit low).
Someone else suggest running the 850 which has 130 watts per channel but not bi-amping. As that would be overkill.
That confuses me. If 100 bi-amp is really 100 according to an rms rating... not 200 than it is too low... Wouldn't 130 bi-amped be just about right?
I don't need all the 850 offers and would prefer to get the 750 I just don't want to damage the speakers by underfeeding them.
Could someone please help me understand what these speakers really need?
Thanks,
Brian
