chains? - the ultra narrows? I'm using a KMC x10sl with no problems but have a Chorus 5.9mm still in the box - would like to use it as my alternate chain but will not fool with anything that wants its own $100.00 chain tool (unless one wants to sacrifice their first born, according to the warnings against using standard chain tools ) but more importantly, cant be removed easily.

Sincerely,

Bill
