Yeah, the chain has plenty of length with the small/small sizing. Rear cassette is Shimano 11/28 so it's one tooth smaller on the big than the equivalent campy size.
Even at big/big, the RD has a good amount of extension left in it - I don't think it's a matter of big/big overextending the RD. When the issue happened I was already on the smaller ring, too...
