I use 11's on the Deluxster and also just strung up the ES build with them. They take a bit of getting used to, but I quite like them now. Much brighter and they don't clash on the frets nearly as much during enthusiastic strumming. I used to run 9's on everything, but in building and fiddling with a multitude of guitars I generally found better overall results from 10's. It depends a lot on playing style really but I can see advantages to using all those sizes, depending on that and the particular guitar.
