Snubber design to reduce EMI and increase efficiency

[rkuris]

The snubber used is a RC (R6 200ohm and C8 0.1uF) across the inductor. I am wondering if it's more efficient and less noisy to use a RC + C snubber. My solar controller will be near some radio equipment and I'd like to eliminate any ringing from the inductor.

There's a good article about this here: http://www.hagtech.com/pdf/snubber.pdf and I plan on doing some testing to make a better snubber.
