looking a little bit of advice. Currently using Veloce on my current race bike; its ok, but temperamental - not ideal when hitting a ramp, trying to shift down and unsure of what gear you're into. Next upgrade will be a groupset, but am not sure which is better, Ultegra or Athena (looking 11spd, but if the argument for 10spd is solid...). I'm a fan of Campy shifting, just unsure of reliability, and the cost of replacement parts like cassettes is frustrating.
Putting it out to the experts...
