Buy the whole Spitfire collection…it’s either that or buy a new (2nd-hand car)

Yesterday, I purchased Spitfire Symphony Orchestra. Today, I had to spend almost the same amount on new tires and winter checkup for my car… those vehicles tend to become a bottomless pit anyway, so go for the samples! 
I have both. 
I particularly like Spitfire’s samples and have just about everything they have put out over the last 10 years, but for the super-dry approach, VSL is going to be preferred. For mockups, Spitfire is usually my go-to to get started (with a smattering of Orchestral Tools and other libraries like LASS and Chris Hein.)
