I've recently done this on my '07 blur as well, but am running a 32t ring. So far it has been great, no regrets what-so-ever. Done a few rides on it now, including one with 6-7km of climbing to start the ride and found the 32 to be adequate. I'd suggest trying it with your current 32t ring and seeing if you want to change it from there..I want to go single on the front of my Blur, but will be staying with a 34t 9spd cassette for the time being. There is a a fair bit of climbing in the granny where I ride, so I guess I'll need to go for a 28 or 30t front ring and sacrifice some top end until I get fitter.
