Hey muziksculp. Here's a suggestion: how about installing only the close and mid mics and the room mix? The installation process makes this possible. That way, you would cut down the total disk space requirements by quite a bit and would still have a pretty good idea of what the library can and can't do. With the standard library, not installing the main + main center mics (why are these separate anyway?) would save you around 94 GB.
The Synchron Player comes with some mixer presets for all sections - close, classical, wide, distant, ambient. The mixes are done very well, are good starting points and should cover the most needed sonic characteristics. The cool thing about these is that if you're going with the room mix versions of the presets, only the room mix, the mid and in some cases the close mics are required. The room mix is kind of the bulk of the sound and you dial in mids (and if needed the close) to taste for more or less close and direct sound.
I spent some time comparing the room mix versions of the presets with their decca multi-mic counterparts and honestly, I think they hold up very well and I don't hear any noteworthy differences between them. The room mix versions sound a bit "roomier" and more airy due to the fact that the mics from the full library have been baked into the downmix as well, but that's not a bad thing either, right?
I think that room mix + mid + close could quite possibly be sufficient for many users. I'm thinking of going this route for the time being and yanking the excess mics from the drive, because I too can't justify having such a big library taking up all this space - not considering the limited number of actually good sounding articulations available. But there are some things about the library that I really like - the overall sound and clarity, the dynamic shorts, the beautiful and musical soft longs, the pizz - and that's not a bad thing to have in the toolbox.
So I suggest installing only the three previously mentioned mic positions, making some music and getting some actual first-hand experience with the library and the player, instead of relying solely on other people's opinions. Maybe you'll find things about the library that you like. That's exactly why many of us are so adamant in pointing out the flaws and shortcomings - because there's a lot to like and with some revisions and additions, the library could still live up to the usual high VSL standards and be absolutely killer.
On a sidenote, the existence of these presets already show that SyS was of course not conceived as a library that's tailored to just one specific sound, and the objection that you're expecting something from it that it can't possibly deliver is of course mistaken.
