Ive had the spitfire studio woodwinds core for awhile now and they are really nice with the right reverb. That being said...the extra mics that come with pro make me want to upgrade for sure at the next sale. The programming for SSt WW is really good. Regardless...if CSW is even close to the quality CSB or CSS....ill buy it for sure.I've been needing a proper Woodwinds library for ages now. Still don't know whether to wait for CSW or just go for Spitfire Studio Winds or even Symphonic winds while they're on sale.
