Have no experience on road bikes With V's or Side pull brakes. However my Giant OCR had brakes that I was never happy with from new. I tried changing pads to no effect and they always had me worried. Changed the brakes over to Shimano 105's and I finally had brakes that worked.
I presume it would be the same with any brakes- some work and some don't.
