Type of Strings?

[mandofocus]

Does anyone know exactly what kind of strings Sean now uses? While I was oogling over Chris's mando that was still on stage, I noticed that there were two boxes of Elixir Strings on stage. I was curious as to what kind they were.
There are several different kinds:
Custom Light
Extra Light
Light
Light tops/Medium bottoms
Medium
Custom Light w/ Ultrathin nanoweb
Light w/ Ultrathin nanoweb
Light Medium w/ Ultrathin nanoweb
and Medium w/ Ultrathin nanoweb.

If anyone knows please let me know. (I have a hint that it is either Mediums or Light tops/Medium bottoms)
