I have a formula lockring on my bike, they are indeed well soft with each notch very quickly bcoming rounded, but using care you can get them to last a long time.
Instead of going straight at the lockring with a hook spanner, follow this procedure:
Get chainwhip, rotate anti clockwise (reverse to drive) the sprocket so it tightens up even *more *against the lockring.
Then do the same thing clockwise (forward drive) on the sprocket.
Now check your lockring, should be a lot looser, in my instance I could screw it off with my hand.
Using this method means the durability of the notches of the lockring is much less important, so you can get by with a formula one for a long time.
