I use multiple springs of varying tension on the strap lever......eliminates any "hitch" problems. For any ancillary pulls where the guitar body doesn't have to be supported, and although the tension of the string itself COULD return to pitch, it would feel mushy...I use a spring assist that pulls the bellcrank into a deadstop, and gives the second or third pull some resistance. The pullstring changer itself also uses spring assist to return to "Zero" position.... this way the string only plays a small part in the return to pitch, as the mechanism theoretically, will return to "Zero" with no string attached.
The strap lever also has an adjustment of plus, or minus one pound of resistance...........Didn't mean to hijack, just responding to the "hitch", and lever resistance/tension concerns.
