what cafeathers is trying to say, heavier will result in some what in tone change. i would be reluctant to change from 9s to 11s, with out knowing what im doing. i respect the fact you are eager to learn to do your own setups. believe me, its not easy, youll need practice, however, practicing on your 1200 dollar strat.
you need to adjust truss rod in order to suport the heavier gauge.
you need to adjust action, intonation and tremolo claw.
youll need ruler that measures in 1/32 and 1/64. adjust also brige height.
if your off in any of those, your guitar will result in BUZZ, or out of tune to itself.
your playing on an american strat and blues junior.
why not invest on a blues driver, or ts 808 something with increase in drive.

Every thing blues strat said is on the money.The only thing I can add is your going to be in for a suprise when you bend 11s are thick a loy of metal to push.You are deffinetly going to need a setup or your neck is going to bow.Hey Hendrix played with 9s and 10s.If you want a heavier sound you could of just tuned down a half step that will fatten you right up.I read an interview with Billy Gibbons who said he always played with heavey strings for the sake of tone till he was touring with,I forgot who who told him he used 9s and thats what he has been playing for years.Hey I am glad your into the tone of your ax because that is the most important aspect I mean guys who are not fretbord wizards are are respected for there tone and then you have most shredders who have the worst tone in the world.Some of my favorite tone meisters/SRV-VANHALEN-SANTANA-GARY MOORE-HENDRIX-BRIAN MAY-CLAPTON-BB KING-ERIC JOHNSON
