Are new valve locks necessary

Almost all of my locks look like this , I had a chat with Brian at IMM and he told me he has abandoned the Comp locks and retainers altogether in favor of having a third party make them for him after too many problems with the Comp stuff . I am waiting to recieve a new set of comp springs and these third party locks and retainers right now. I was at Inertias place yesterday and he has just recently discovered several cracked Comp retainers on a set of heads he was doing so if you guys want to keep trusting their products have at it but I'm not ruining pistons and a set of heads , this was too close to a failure already.
