My workflow with the 28S is usually:
1. Unshift, open the aperture, compose the frame, close the aperture, green button meter (I may take a digital preview shot and chimp the histogram).
2. Open the aperture, shift, recompose, close the aperture, shoot.
Although it feels like a lot of steps, it goes very quickly once you've done it a few times. The two-ring design of the aperture controls makes it easy to set the desired shooting aperture with one ring and then quick-slide the working aperture between full-open and chosen-setting for the various metering and recomposition steps.
The trick with OVF metering the 28S is that it has to be unshifted to meter properly. OVF issues also imply that composing on a heavily-shifted setting often requires the aperture to be fully open. If you use a tripod and LV, that might simplify things but I never travel with a tripod.
Other tips:
1. To eliminate keystoning: use the camera's electronic level to level the camera. Then adjust the vertical composition by shifting the lens (but keeping the camera level).
2. The built-in hood has 77mm threads on so you can use a filter (Note: a normal thickness polarizing filter does not vignette on APS-C but does on the K1 at >10mm up-down shift in landscape orientation and >7 mm left-right shift in landscape orientation along the length of the frame).
3. You can do a quicky 4.8:1 aspect ratio landscape panorama taking one shot with the lens left-shifted all the way, then rotating the shift-direction-angle 180° and shooting with the lens right-shifted all the way. (Note: this does have 22 mm of parallax error so it's best suited for scenes with no close foreground objects that sticking up in front of background objects.)
P.S. There's no problem with physical clearance between the lens and K1 body so one can shift in any direction.

My minimum international travel kit is a K1, Sigma 12-24 DG, Pentax 28/3.5 shift, Pentax-K 50/1.2, Pentax DFA 100/2.8 macro, Quantary 70-300 with the lenses fitting nicely in a decent-sized Lowepro waist pack. The waist pack has enough room for a couple more small lenses so I often add a Pentax-F 35-80 for casual on-the-good shooting, a 2X teleconvertor, and a stack of 49 and/or 52 mm filters, spare batteries, my wife's P&S, and a stash of emergency cash. The camera body (with one of the smaller lenses) goes in small Pentax camera case with belt loops that can be threaded through the waist pack belt for carrying on the plane.
