G1 Ironhide/Ratchet: I bring the shoulders right in so that the shoulder joint sits flush against the grill in robot mode, which gives it a more "War Within"- esque look. The outstretched shoulder struts work when you're talking about a power lifter on a tank tread battle station base, but not so much when you're talking about a humanoid robot.

G1 Hurricane: The position of the shoulders on the instructions makes it looks like Hurricane's arms are attached halfway down his ribcage, so I slide the shoulders up to the point where the arms just have clearance still, which makesit look 100 times better.
