I did change from 10s to 11s on my strat and really couldn't hear much variation in tone, if any, but maybe if I'd upped them to 12s I would have? I later reverted to D'Addario 10s for their playability.
I currently have Ernie Ball 10s on the Burns with a wound third - the problem of a wound third being slightly quieter resulted, but I've adjusted my playing style to accommodate this volume variation and it's not as obviously quieter as when I tried a similar trick on the strat fitted with 57/62s. Not so easy to bend, of course, but a gentler, smoother sound in my opinion as I've always thought the plain third to be overly strident on the Burns, unlike the strat.
Cheers,
Martyn
