Agree. Bicycles are pretty efficient. I can throw 10lbs on my touring bike, which weighs 6lbs more than my road bike, and I don't notice a whole lot of difference riding up my favorite climb (3.5mi, ~1400ft). My overall speed is a bit slower, but either way climbing feels like work...
You will, however, notice a difference as your fitness improves. Even if you don't reduce your weight by a pound, improved muscular and cardiovascular fitness will pay dividends while climbing.
