What wheels are you coming from? That might make a difference re: noticing the weight.
I had some nice handbuilt wheels - niobium 27 w/ white industry hubs - that had plenty of miles on them before I destroyed them hitting a giant pothole. I don't remember the exact weight, but it was somewhere around 1,400g.
While deciding what to get next I used my backup wheels, some Mavic Aksiums, which I think weigh close to 2,000g.
I decided that instead of going for one pair of somewhat light, somewhat aero wheels, such as wheels built around the pacenti sl23, I'd go for the (possibly) more aero and less expensive Flo30s and then I'll get some "event" wheels at a later date.
I've been riding the FLO's for about 3 weeks and I love them. In that time I've ridden both Breathless Agony (12k ft climbing) and Heartbreak Hundred (8.5k ft climbing) - I didn't get the slightest sensation that the wheel weight was slowing me down. Maybe I was desensitized to the weight because I used the Aksiums for a bit, or maybe it just doesn't matter that much for most climbing. I do know the build quality seems nice and the ride quality has been great. The wider rim does seem to put the tire in better shape for cornering; I really enjoy the road feel.
How's the brake track? Still black? Chris from FLO told me that anodization will eventually wear off on the brake track.
