No thunder here...
Its simple, if you bend a crank a bit (yes, it requires experience to know when it is a good idea and when its not - ie, too far gone) it will bend back easily and stay there, no weakness.
Come on, if you have a bend 15 or 20 thou, its not like its 45 degrees over.... bend it back and its good to go.
DOnt beleive me, I dont care. Spend your $$.
(ps I hate to have to justify anything, or state my background, etc. Just do what you want... and so will I )
