A second question on durability: is there a difference in likelihood of surviving a "routine" slide? The old aluminum levers pre-index almost always survived crashes (at least if you weren't concerned with looks). The newer levers (like Tektro) do far less well. Are there brifters that have better or worse survivability? (I'm thinking a heavier model like Sora might be considerably better.)

I have yet to own brifters. DTs work, are cheap, light, versatile (cog spacing and number matters zero) and I know how to use them.
