Look into the weights of the rims. Velocity deep V's are not light! And a few grams saved at the wheel's periphery will soon be felt at the pedals. Besides Velocity deepV's are not really commuter tire friendly unless you like 25mm tires. Sure they will accept 28's but the sidewalls will be ballooned out quite a bit and that'll make it hard to get the wheels out from between most rim brakes. Frankly having done bikes with some semi deep v's and lighter small box section rims I far and away prefer the lighter box sections for in town commuting. Yes the aero rims have a speed advantage but with the intown stop and go and limited speeds on most paths to avoid disasters I just never found that I was able to in any manner see a benifit. If your commute is long stretches of steady riding at higher speeds then that's a different story. The point is to suit the wheel build to the most regular route dynamics.

You may THINK you're wedded to that frame but think again. You'd soon be just as taken with a new frame if you had one. And if you were to get a single speed frame it would be far more IGH friendly due to the horizontal dropouts. That would eliminate the tensioner or playing with gearing that gives you just the right length. And don't take the losses you get from using a tensioner lightly. Backspin the pedals on a bike with a derrailleur and then do the same on a single speed. I've had a few bikes to try this on and the difference is amazing. It's not a lot but it's easily felt as that "little extra bit of energy" when you're in the saddle.

Anyhow, that's just the flip side of the coin for you to consider.
