In reply to PaulJepson:
Yeah fair enough, if it's hangers with a single mallion on then that's ok, you're not making the lower off any worse (in fact you're improving it). No issue with that.
I just get annoyed when there some kind of perfectly serviceable lower off, say rings or threadable staples, and someone has left a mallion on which has now rusted shut meaning everyone else who lowers off the route now has to thread their rope against and have the rusty sharp edges of the mallion rubbing on their rope.
That's not what you were talking about though doing though, so you're all good and my apologies offered!
