For what it's worth . . .
I just installed a pair of Soma Sparrows and so far I'm loving the feel and position. When they're in the stem with a drop to them, it gives them a definite "cafe racer" feel. You're definitely in the cockpit of the bike, as opposed to riding above it. Flipped, with a rise, they have more of a "townie" feel to them. They'll need a little more riding to dial them in, but as of now, I'm really digging them.
