This is what I do. One arm gets tired switch to the other, isn't that why we were born with two arms?
How many of you switch arms? I started doing this very early on, as I was concerned about a repetitive stress injury. It's a little awkward when you first start, but with practice it will become comfortable. When I'm gridding an area, I will typically go one direction right-handed, then come back the other left-handed. It helps to keep both arms fresh, and I haven't (yet) run into any elbow or shoulder problems. Otherwise I would agree with the advice to tweak the length a bit. Just a little shorter will take some of the weight off of your arm.
