I picked up a set of black Koolstop brake blocks for my bike as my current pads were getting worn, they look odd due to the scraper edge but I liked the idea, they fitted as expected and looked the dogs nutts 
However in use its a different story, ok so they were new and I knew they needed bedding in, so 10 miles light and hard braking is all that I've ever needed on any brakes, but these are scary. I did the norm bedding in, they felt squishy and soft, in fact they really didn't seem to stop like they were meant to, but I carried on in hope. I did a 50 mile loop, the back brakes settled down quickly but the front clicked, juddered and felt seriously wrong.
In fact on one hill, I forgot about the brake issue and was riding in the traffic flow at 40mph, when I went to slow and finally stop it was almost a brown trouser moment, they DID NOT want to stop me, yes they slowed me but I was pulling the brakes like my life depended on them, well it did and I wasn't sure they would stop me.
Once home I ripped them out, they were all bedded in perfectly, but they are crap in my mind, they are now in the bin never to be used or bought again, tomorrow i'll be right down the LBS to get some Dura Ace ones, I know they don't last too long but they do stop me.
