" I'm going from 3H to 10H."

You're risking significant response ripple in the filter with that value. Large values of C will be probably be required after that choke in order to smooth the response and output Z.

EDIT: So as not to be misunderstood, 10H is excellent for eliminating hum and noise, just be sure the overall design performs well in other respects as well. I use SPICE to analyze the output Z of all my supplies. That - plus PSUD - will tell you just about everything you need to know.
