I need lower gears 4 hills on my road bike

[luv2climb]

The Specialized Amira Sport I bought back in July came with a 50/34 compact double and a 12-28 cassette. I ended up doing the paperboy switchbacking (traversing) on the steeper 14%+ stuff, so I bought a 11-34 cassette, a Shimano Deore XT 9-speed MTB derailleur, and a SRAM 10-speed chain. The bike is 10-speed, but there are no current model Shimano 10-speed MTB derailleurs that will work with Shimano 10-speed road groupsets (this bike came with Shimano 105).

I weighed the 105 and Deore derailleurs and the Deore is only 1/2 ounce heavier than the 105. Not bad for a long-cage MTB derailleur!
