I'm interested in hearing suggestions for strings to use on the Prince O3 line of racquets. Anyone have some favorite strings for these rackets, and why?

I started stringing a couple months ago and received a ton of free string with my stringer, so I'm going through the Gamma supply they gave me.

Gamma Revalation 17 gauge, strung at 56.5 lbs, has been my favorite thus far.
