I haven't read any threads on 11 gauge strings. Do you use them? Why?

I have 11's on my 22 Semi-Hollow, LTD for extra tension and thicker tone. I use this guitar for jazz and blues in standard and open tunings. My DC3 also has 11's and is kept in standard tuning a 1/2 tone down, mostly for rock, blues, and country. Since it's kept a 1/2 step down, the tension of 11's feels better to my fingers.

How about you? Which of your PRS is set-up with 11's and why?
