These were my thoughts exactly, the weight saving are negligible when you're a veritable lump like me [84kgs].
Also, 3 punctures in the front wheel in 3 days with the new wheels, I think its the tyre though as the back wheel has been fine. Very annoying though, especially as the pro4's in black 25mm are out of stock on wiggle. Will have to wait until I'm back from Sziget.
The punctures aren't on the inside of the tube, are they? It could be the rim tape is skewiff, leaving a spoke exposed, which could pop a tube.
