That is far from light, but still much lighter than many stock wheelsets. I was shooting for a moderately aero, super stiff, and <2000g wheelset for a solid training set and a passable race wheelset in one. Easily the stiffest wheelset I've ever ridden, and they put up with a beating. I wouldn't hesitate to lace them 20/24 and use them on the road.
Oh, they also look pretty badass. H+Son does some of the best metal finishing I've seen on rims.
I'm really not getting the logic of these rims. At 615 grams they are boat anchors. You can get nice strong rims that weigh much less.
The 40mm depth could give you some aero advantage, but a 32 spoke wheel is going to give all that back.
For the OP, at 145 lbs, a 615 gram rim, particularly with 32 spokes, would be gross overkill.
