To each their own. I've personally never see anything good about their Evo cams (DSM ones seem ok) and I've seen a few pics of broken BC valve springs. I've also seen people float valves with the BC springs when the stock springs weren't. Every car and setup is different though so take everything with that in mind.
The bc valve springs measured perfect uniformity on the sets we've tested (spring pressure). If the springs are breaking it's not from the spring, it's something else causing it. For example, I have some broken cosworth dual springs with broken inner springs here right now. It's not cause the springs suck either.... It's from the cam that broke which bent valves an broke the springs.
I have seen stock sprigs break with no explaination though. They are definately softer then the bc springs too, so again, you should never see valves floating with bc spings before the stock springs float.
