I have a Merlin Agilis - it definitely isn't too flimsy. It's nice for general training rides, but it wasn't until I started doing crits that I finally appreciated what this particular frame was intended for. It is very nimble. In terms of ride quality, it probably doesn't dampen things out as much as CF, but you definitely have great road feel. And after 5 yrs, it looks like it's brand new.
