I have been using NE white Safety Blue (1/2" or 13mm) for 4 years with my Petzl paired ascenders (toothed cam) for SRT climbs, about 85 ft in my case. I usually do this climb 2X, back to back for a cardio and strength workout.
I have not experienced any problems running 13+mm line thru the ascenders.

In all my gear catalogs, 11mm line is the recommended diamater for SRT and mechanical ascenders.

What exactly is the advantage here? Is it a safety issue - the 11mm is a better "fit" and therefore less likey to jump the channel?
