Road Wheels & Road Wheel Recommendations?

Would it be silly to build up an A719* rims for a carbon sportive bike over the A23?

*I was offered 2x 32h A719 for silly money.

What use do you have for 150g per rim weight saving? If you were in a hurry, you wouldn't be considering either rim.

I'd usually disagree with Tester on this one, and say lifes short, the time spent riding even shorter, get the lighter ones.

But that 150g extra weight includes a 6.5% increase in width, and eyelets. So its a fairish trade off IMHO.
