Should I keep hanging on to Campagnolo 10 Speed?

[baldbones]

New bike time and the end of year deals on Ultegra bikes are really good, I’ve benn hoarding Campagnolo 10 for years and can’t decide whether to sell it all to get a better bike with Shimano. I’m looking at a Cannondale Super Six which frame only is the Hi Mod is out of my price range. Or I could buy it and sell the shimano stuff. I’m feeling like it’s time to let go...
Any advice or thoughts
Thanks!
