I would look into whether these rims are welded or pinned. If I remember correctly Velocity pins the rim opposed to welding.
I e-mailed Velocity asking if their Aerohead and Deep V rims were welded or pinned at the joint. Here's their response:
"All of our rims are pinned. Its not your ordinary process though, its a fairly elaborate process. We have an extra piece of extrusion that matches the inside of the rim that is joining the two pieces through a special heat activated epoxy. It works quite well. Let me know if you have any other questions."
Keep in mind pinned rims will not affect the life of the rim. However, personally I have found they pulse when braking. Also keep in mind black and anodized metals are not as strong (minor point).
