Hand built wheels are the way to go- providing you find the right builder.
And 6 months into road riding- I went down a hill. Got to 30 mph just coasting and nearly went back to mountain biking. Upright MTB with Knobblies and hand built wheels and I get to 37mph on the same hill. Got a set of Handbuilts and average ride speed went up-Top speed on the flat was higher and Coasting down the same hill---I got 41 mph.
