Well I'm Italian I'm the definition of cheap... I train at home too.
Issue is not so much from elbow it stems from a bad shoulder, it's always been more pronated and internally rotated comparing to left, and that's a problem with most barbell movements... that's why I mostly use dbells, however I feel the barbell to be more effective for skulls.
The super EZ bar offers a near-parallel grip almost like triceps bar, and it's much cheaper than a multi grip. I need a new bar anyway...
