I liked the CW forged cranks. They were a great crank at a great price. But they built them with intentions of them being lower hp builds. Then all the people built high hp cubs, super cubs and DM's these cranks held up ok for awhile. But with detonation, lean conditions and high hp these cranks were broken regularly.
I feel most crank problems are related some how to detonation. People don't realize how this effects every part in a two stroke. Usually for a bad outcome if not taken care of.
I am not saying billet is bullet proof at all. I have broken billet cranks before.
