Quoted from BigAl56:Bally Linear flippers and slings were considered an inferior upgrade per many pinball purists. That is why so many linear flipper games are found converted to classic flipper assemblies. The great Desi D' Percel created the linear designs and could talk your ear off explaining why they were superior. He always blamed the failure of linear components on inferior material substitutions by the purchasing department.

Those linear slings ruined plenty of playfields. They were too strong for the assembly and the whole thing would come loose. Eventually, a too large fastener would be used to keep the slingshot mech in place leading to pokes through the playfield. I have probably seen a dozen games come through my hands with that issue.
