The Cannonade 3 0h was specific for crit, not long day distance and poser as racer rider. Excellent climber. Fortunately and with some modern upgrade, they are fun and easily can change the comfort. Carbon fork, threadless, wheelset with tubulars.
While in the classification of older racing lightweights, I was largely dismayed with a Kestrel 200SCi and early carbon Spin tri spoke clinchers. What a slug in every aspect; acceleration, climbing, cross wind, ride quality, transitional handling, cornering.
As for this thread, every category of bikes will have turds. Penny farthing, to 'muscle bikes with banana seats' not for sporting a thong and riding to the beach. Good luck.
