At the moment, I'm using a 42 Strand (PureSounds) on my MMX 14x5.5.
Depending on how you tune the drum in the first place, it will give you a drier, hearty sound.
The snares itself, I find muffles the drum enough to rid of the unwanted ring -when tuned medium tension (top and bottom)
When tuned higer, I find the snares get a little more lively and gives of more 'crack' -still with a drier sound, compared to the 22 strand.
Hope this helps.
