I pour my own, but this last run used the hitchhikers as screw locks because that is all the BPS had at the time. They look great, but when I used them it was another story. Caught a fish and the flimsy spring bent all outta shape and became nonusable after a few fish. Has anyone used the Do-It ss screw lock inserts? Are they sturdier/better than the hitchhikers? I would even be willing to trade the hikers for some.
