Which drivers for 700r?

Ok, so I know that ASIO is great, but I can't use them do to the fact that you can not share drivers with other cards.  I have the complete vs700 system (700r and 700c), 2 motu 2408 MK2s, a motu 24I/O and a MOTU 24i (dont ask.....I have all of my studio gear plugged in so I can minimize my patchbay).
 
Should I use wdm drivers?  There was another driver I saw (wasapia....something like that-not in studio right now, so not sure exactly what is was).  When I use the wasapia driver....nothing is useable.  For some reason, I that that this driver was the latest standard.
 
I am running X1 with the latest patch.  Before I upgraded, 8.5.3 was SOLID.  I mean 1.5 ms latency solid.  Now, it seems that when I set the vs700 to 3 ms, it crashes. Just looking for help of any kind.
 
Thx guys!
