I have been thinking of switching my campy ergolevers to the newer shaped versions. Reason for the switch would be comfort. I find I spend much more time on the hoods while riding the tandem then when I am riding the single. I am running 10 spped campy levers with 9 speed shimano derailer and cog set, I am happy with the performance of that configuration and would only be switching for comfort. Can anybody offer some insight based on use of both versions of the campy levers? Do the new shifters shift any better or worse than the older versions? Based on expeience does this seem like a worthwhile upgrade?

Thanks
