Having used Ergos since the mid 90s, of course I'll say that this is the way to go. One interesting aspect of the 8 speed Ergos is that the rear, with a compatible Campy der, shifts Campy 8 speed AND Shimano 7 speed (as both use 5mm cod spacing). You can find used 8 speed Ergos for $100+ if you wait and pay attention.
Some of my concerns about the Sora ft STI use is the non spec crank. Whether it's rings are not a compatible C_C dimension is what i tried to describe and suggest be looked for. Andy.
