Lots of people posting real world experience that 5 lb is noticeable and 10 lb has made a big difference. Most concur that it makes the biggest difference on hills, which is exactly what the OP is asking about.

I'm not sure 10 lb will get the OP from 48x19 to 48x17 but combined with some training it should help.

I lived on Long Island which is flat. Coming from the flatlands, riding over the 59th street bridge was a memorable climb and looking up at the Verrazano Bridge from the BQE on the 5 Borough Bike Tour was frightening.

I wish the OP luck and hopes he lets us know how he does.
