I had a Talon for several years - my weight bounces between 205 and 225. The bike held up fine - I only sold it because I got a great deal on a Lynskey, and I wanted a bike with a taller head tube and slightly more relaxed geometry. In those 3 years I probably put close to 20,000 miles on it. The only issue I had was crash damage - I broke a chain during the Death Ride, and it was around 5 am and still dark so I didn't realize what had happened and kept pedaling until the wheel locked up - took out the RD and cracked the seat stay. Not the fault of the frame, though - and Kestrel gave me a decent discount on a replacement.
Note that my Talon was the original model, not the SL (or lightweight) and not the current one - they kept the same kind of aero theme on the styling, but the tube shapes look pretty different on the new one.
FWIW, the ride on the Talon was really very good. Much like the stereotypical carbon bike, it excelled at dampening vibration - very little road buzz got through the fork to the handlebars or through the frame to the saddle, even on the worst chip seal. My titanium Lynskey comes close (actually, the Edge fork on the Lynskey is probably better at this than the Kestrel fork), but has a different, livelier feel. Both are very good. The Talon has some pretty aggressive geometry - something to watch out for. A friend who borrowed it said it was a crit bike, pure and simple. Nimble to the point of being nervous, it's built to take corners at high speeds and accelerate out of them. If you are looking for something like a Specialized Roubaix, this might not be your bike. The head tube is also pretty short - if you want the handlebars up near your saddle height it might be hard to achieve with this frame.
Edit: I'm attaching a photo so you can see what my saddle to bar drop looked like. I have typical proportions (I'm 5'10" and this was a 55cm bike), and I'd used the maximum number of spacers recommended by Kestrel for that fork, along with the stem flipped up.
