There are so many different snare drum sounds in drum n bass... You can either hear a fat sound or a high pitched sound and everything in between. I would suggest two snares - one for your fat snare sound @ 14 x 5+ along with a secondary snare of 10'', 12'' or 13'' - depending on the tuning. I do this when playing DnB on an acoustic kit or with an electronic kit...
If you're looking for one snare to cover it all, I personally find my Akira Jimbo snare is great for DnB because it sounds rather unique and I can play more towards the edge for higher-pitched notes. It's also what was intended for this snare on a certain level... I find 13'' snares can be rather versatile, but the saying ''jack of all trades - master of none'' can also be true in this regard...
