[quote="Adam"]I've just heard stories that discs can make a minute difference on a 10?
No chance. A 10 is a very short difference and that would be a huge percentage increase.
As Jon said with your bike and wheels, a skinsuit, a pointy hat, and some good tri-bars you'll have a very good setup which won't be far off a full TT set up. The main difference will be having to get out of a tuck to change gear as you won't have bar end shifters.
When I say good tri-bars that's not always expensive but ones that suit and fit you well. It'll be different for everyone as to what suits you (mount above or below the bars? bent extensions or straight? length of extensions? width of pads?) so try a few out if you can before buying some. Ones with a plenty of adjustment would be good to give you plenty of tweakability before you find what works best for you.
