Write performance was better with protocol A than it was with C. Switching protocols was easy, though we weren't working with live data when we did the switch. There have been two unplanned flailovers in the last 8 months, but even with protocol A, there's been no data loss yet. Note that YMMV on this, but it's worked for us.
