I was having this same delusion during the end of last year while I was still doing stronglifts.
I sucked at cleans, I used to split and jump forward and my racking was terrible.
So I decided to work on partial movements like power shrugs and high pulls.
Important things I did not quite realise were, that the power clean is NOT in the programme to build back muscles. It is the element that transfers the strength developed in squat and deadlift into explosive athletic power.
Other similar programmes that involves rows make you think you need a muscle building exercise to mirror the bench press (push/pull) But that is not Starting Strength.
Also, there is little point in choosing high pulls over power cleans. If you suck at power cleans you will suck at high pulls too. Just work on your racking.
For me choosing a much narrower grip helped a lot.
Partial range movements like high pulls or shrugs are for more advanced trainees. Just like an advanced lifter may train halting deadlifts & rack pulls.
Rip provides really good advice, so I for one am following it now.
