I have the 72mm, it's an excellent performer, even wide open.
I'm interested in the 60mm, problem with that is it's small image circle, only 60mm according to spec (the 72 has 90mm). There's a new 60mm f/5.6 with 110mm image circle, but it's a lot more expensive. So this is an alternative for those of us on a budget.
I'm wondering how much you can shift with this 60/4 lens. If it really is exactly 60mm image circle you could not shift my 36x48mm sensor at all (it has 60mm diagonal), front tilt would be problematic too. If sharpness falloff is not too drastic one could maybe shift a few mm. Do you have any information about this?
