Go with the A23s.
My first set of handbuilts were based on Aerohead-Aerohead O/C hoops. I liked them a lot. Nice balance between weight, cost, and strength. They wear 25mm Conti 4-Seasons.
My second set were built on Velocity's now-discontinued VXC (700C version) rims with Velocity's road disc hub in back, Shimano DH-S501 dynamo hub in front, DT Competitions laced 3-cross with brass nipples all the way around. Those are my bulletproof commuting wheels on the Portland, my four-seasons all-conditions commuter. Absolutely flawless in their intended role. The were also my first wide rims, which I found I really liked, with both the 28mm Conti 4-Seasons in the three-seasons, and the 38mm Nokian studded snow tires. So...
My third set was a Velocity-built A23 PRO build, 20/24 Sapim CX-Ray spokes, Velocity's road race hubs on both ends. Those are on my Litespeed, and shod with 25mm Conti 4000S. I'm nothing less than delighted with them. Three years now and I can find no fault with them. Even on the cobbles that form part of my commute.
I'm retiring that first set of Aerohead-Aerohead O/C wheels. Not because they're worn out--not nearly. But I really like the wider rims on the other bikes. So I've been looking for an excuse. Last month I upgraded the dynamo lights on the Portland, so I thought I'd put the old lights on the Ribble. Thus, I needed a new front wheel with a dynamo hub. Might as well get a pair, right?
Handspun built a front wheel to my spec--32-hole A23, Shimano DH-S501 dynamo hub (just in case I ever have to use it on the disc-brake-equipped Portland), DT Revolutions laced 3-cross, with brass nipples. Handspun doesn't build with Velocity hubs, so I had the LBS across the street build the rear. I pick it up tomorrow--32-hole A23, Velocity road hub for Shimano 8/9/10-speed, DT Revolutions on the NDS, DT Competitions on the DS, 3-cross both sides, and brass nipples.
Just switching the front from an Aerohead to an A23--moving the same tire and tube over--made a distinct difference in the ride and handling of the bike.
