I love them, but the interwebs and my masseus says they are bad for my shoulder. What is an alternative exercise to work traps/neck/all that stuff?

Chinups (pronated grip):

If I do them with a very wide grip, does it exercise a certain muscle more than if I do them with a shoulder wide grip? if so, which one? and which is a better option? I like doing them wide but it means I can't do as many.
