placing the order for wheels from dcr in the next 10days hopefully - but switching the hubs from novatecs to shimano 105's
so its the velocity a23's, with sapim race spokes and 105 hubs - built in 28/32 ( rims are 23mm too, so should be a nice plush and smooth ride)
The 105 are really good hubs, very strong and quiet. I have a set of wheels with them for my winter bike. As long as you keep the hubs with enough grease and the cones not too tight your hubs will last you a very long time. It takes some practice to get the cones just right.
I'm quite happy with my Novatec hubs too although I'm quite heavy so I expect them to need some attention before too long. They are substantially lighter than the 105 and for that reason I bought them.
Depending on your weight and style of riding you can go as low as 24 spokes on the front wheel. I was going to go 28 spokes too but then I wanted a radial lacing pattern and 28 spokes would put too much stress on the hub so I went for 24 spokes instead and with a little less tension than a cross pattern would need.
I should have gone with 36 spokes at the back but I got 32 Sapim race spokes instead. I'm heavy but I don't ride too crazy. I'm aware that the life of the wheel will be shortened but I can live with that.
I also think the OP should get some hand built wheels.
