Re: a "picks up everything" kinda mic
One word of caution about selecting a condenser with an omni pattern is that you really need to have a good sounding room, because you're going to be hearing a lot more of it with an omnidirectional mic as opposed to something with a cardioid pattern. The OP described capturing a lot of percussive elements, and unless the room sounds great and you want its reverb on every track you record, you may be better served with something more directional with a tighter pattern. Sly's recommendation of a mic with switchable pattern options makes good sense. But I would suggest a cardioid pattern as the main consideration, with the possibility of omni as an option.
We live in an era when we're spoilt for choice with affordable condenser mics, many of them with very similar Chinese made diaphragms and similar electronics. They may not sound as good as an old Neumann (well, in fact, they don't!) but then we aren't running them into $12,000 mic pres either, so everything can still be to scale and still get some very satisfying results.
