I bought them on special for $75 if I remember correctly. I was just looking for some new strings as I only had Garritan at the time and the advertising sounded pretty good. They are useable but out of the box they need a little coaxing to my taste. They are nice just to drop them in DimPro and go to work.
However, they do sound a little long in tooth compared to the newer strings that are available now. I find myself using Miroslav 2 and GPO 5 more than anything but I will probably continue to layer them with better libraries. If you don't have strings at all they are worth the sell price but $150 is a little steep IMO.
Michael, I have the Korsakov book as well. I have boxs of orchestration technique books. I started out at age 10 to be a classical pianist and studied thru my teens. You are correct assuming that the same skills are needed no matter what kind of music it is.
