Seems to me that the upper spreader has to be set "up" more of an angle, because that cap shroud does such a radical angle back to the mast head once it leaves the upper spreader tip .

Take a look at a double-spreader rig; I don't know that I've ever seen one where the angle from the upper spreader to the mast is greater than the angle from the lower spreader to the mast.
As for looseness at the spreader roots, on the one hand a little bit is not necessarily a problem. On the other hand the looseness might be the result of undersized pins, or holes that have been worn or torqued into the spreader, so examine carefully.
Fair leads,
