Having recoed a few sets of older-style Ergos by merely tweaking the index springs, this would be my first thought; it's likely just a case of tired springs rather than wear... although not having had a chance to inspect the guts of later Ergos, I could easily be wrong.
I saw the guts of some Doubletaps at a bike show a couple of months back, and I've gotta say they compare very favourably to Ergos and STIs from an engineering perspective; such a beautifully simple mechanism. Doubletap looks like it may eventually succumb to wear, perhaps being less durable than 1st-gen STIs (which mostly only keep working long enough to wear out if they're overhauled to replace the crappy grease), but the next brifters I buy will be SRAM for sure.
