SDC pairs may be more useful for you, but a pair of LDC would also be something you'd find uses for (maybe, perhaps , more for vocals)
For percussion, congas, bongos, I usefully place one at the bottom and one pointed at the heads, in which case the mics would need to necessarily be a 'stereo" pair
mic technique is something think many overlook- had I not initially interned in a commercial studio i would have just stuck a mic somewhere close and went with it, but position to the source and in the room, really does play a big role in the sound you get out of different mics, and there is a world of difference between mics of all shapes, sizes, and prices, AND the pre-am has a big impact as well
It would be hugely convenient is there were just a few types of mics, and then you had 'em ....but noooooooo such luck
You may find that you buy and sell and trade a lot of mics till you settle on your 'go-to's"
