I jump between 30, 30.75, 32 and 34 scale instruments all the time. Once you're used to each individually, I find it's only a moment after switching basses to be back in sync with it.
For strings on shorter scales, I like EB Hybrid slinkies (stainless), DR Hi Beams and have some Status Graphite round-core sets on order. The Status' are excellent on my headless basses and I'm hoping for the same on the Alembics.
