So after running loopadj, I do seem to get slightly improved lineshapes:

IMHO, they're still not perfect, which I'm still looking into. One issue is that the lock phase seems to drift quite a bit with repeated calls to loopadj--it seems to drift between 55-65 degrees. The loop parameters (loop gain, loop time, etc), however, are highly converged and do not fluctuate between multiple calls.

FYI, this is what my lock looks like during the gradient pulses. I'm not sure what normal is here, though.
