Nonsense!
Do you even know how the Park FFS-2 works? It isn't controlled in any sense. It isn't a precision tool. Its totally subjective to the force the mechanic YANKS on it with. If the mechanic is pulling up along with out, he doesn't just spread the chain stays out, but he incrementally bend thes dropout "up" along with what he was trying to do in moving it out.
The Park FFS-2 is a terrible tool to use to cold set a frame. All you want to do when cold setting a frame is spread the chain stays as equally as possible, in a plane, without introducing all kinds of other dynamic bends that have to be corrected.
Park makes some really crappy tools. The FFS-2 is like using a hammer and duct tape. Its the wrong tool for the job.
