Of course it makes the most sense to grab all and try one at a time if you're tight on space, then pick'n-choose from there. Fortunately, some of the banks have great creative values. The "sforzatron" pack alone is worth the trip, for its vast sound creation capabilities (and luckily comes with loads of preconfigured ones for the likes of us who don't speak Parameters)

Just because you can, doesn't mean you should!
