I have the standard Engelhart endpin w/ the screw and the slotted endpin...but I don't want this kind, I'm REALLY sick of it not catching correctly on the screw and etc. What kind of endpin systems are there? What are the benefits to this "aircraft cable" thing between my endpin system and my tailpeice? How much does all this stuff cost? Would I be able to do it myself without much knowledge of DB construction? etc... ANY advice would help! Thank you.
