Thanks to all for your replies! I've played violin and cello just enough to know not to "play" them as I would a keyboard, and to not be in love with most of the string samples I've heard/own. I've listened to a few of the GPO demos, and I think it would definitely give me better results than what I'm getting now. Just being able to get more realistic articulations/bowings would help a lot.
I actually have Rimsky-Korsakov's Principles of Orchestration around here somewhere...
I might go ahead and spring for GPO rather than spend much time with the Dim Pro subset, since it sounds like the parameters are handled differently and I don't want to learn one way only to have to learn another.
Just thinking out loud, as you can tell, but thanks again for the input! I gather GPO is the best orchestral library near this price range (always a consideration)? $200 at zzounds, but I haven't shopped around.
Oh, and what do you think of the woodwinds & brass? I read one very good review of the flutes somewhere today.
