If your after reliability (which from memory I know you are) then a 9mm is the more reliable option.
By running an 11mm pump your putting the engine under a lot more strain especially seeing as you'd probably be running in excess of 30~40PSI!
If you don't mind swapping engines then go ahead, paired with a big blower it's amazing gains (as many have proved such as Darren)!
If you want reliability, then follow Dave and JP's 9mm choice. Again, they have proved that 9mm's are more then capable.
Also, the highest powered XUD I've seen proven on paper is running a 9mm and hasn't blown yet.
