Hey Doc long time no follow up. Your Strat looks and sounds awesome. Nut looks good. I use 10s on all my Fender guitars (7.25 & 9.5 radius fretboards). To my ears it contributes positively to the overall tone.
Cheers mate, I reckon that putting 10s on Strats tends to mellow them out a little bit so that they're not so ice-picky like they are with 09s, plus 10's seem to produce more output.
