Mixing shimano 10sp chainset with 9sp drivetrain?

[Ticketty Boo!]

My Trek is equipped with 9sp Dura Ace 7700. Am looking to replace the chainset. Has anyone ever tried running a 10sp chainset (ultegra 6700) with a 9sp chain?

Am I daft in thinking that the only issue will be a slightly thinner chainring?

Re:

I've used a 10 speed Truvativ road triple with a 9 speed Shimano chain and it worked just fine.

I've done it both ways, 9 speed chain set, 10 speed driveline, and 10 speed chain set, 9 speed everything else.
The differences in thickness aren't enough to affect how it works

I've run a 10 speed chainset on 9 speed for over a decade now. No trouble.

I've even thrown Sram in the mix as well and it still worked

Thanks for the replies. Have bought the chainset and BB and looking forward to trying it out.
