But then I discovered this too:

I prefer a 90-degree plug on the strobe side to relieve cord stress, and not have yet another cord sticking out the back of the unit. I've actually damaged the 1/8" connector on my B1600 from bumping the sync cord on a wall. Ever since getting it fixed I have always used 90-degree plugs.
