I ride Campagnolo and I've ridden Shimano quite a bit too. I'm just going on hearsay but it's not as though this is something very few people are complaining about now is it? Sure, it may just take some getting used to, but why should you have to relearn something you can already do instinctively with another more familiar group? It's not as though SRAM is bringing some other added benefit to the table that Shimano and Campy don't have.
