Well heck, there's a derailleur adjustment option I haven't considered. If ya got chain rub, just cut part of the cage then bend the other side till it breaks off. You should post that in the repair and adjustment section. Come to think on it, me good ol'brodder, Who has actually worked as a paid mechanic too, thinks; once he's lost or striped a bolt, beat em to death, or mangled something like this, resounds on: "It's OK because they always put more bolts or in this case, metal than needed" Might have fixed the chain rub problem for you years ago.
