Default Halfshafts for IRS: solid or tubular?
In doing some general reading, I came across references to differing views on halfshafts. What I used to assume was, that, since most of the tortional energy is transferred or carried by the outer "skin" of things like drive-shafts, the same would apply to halfshafts going from the differential to the wheels. I noticed some Fords, SPFs and some others feature SOLID halfshafts. Butlers and others with modified Salisbury units went with strong (thick-walled?) tubes. Which is preferable? Better yet, which is stronger or more immune to distortion (twist) etc.? SPF offers a stronger upgrade---but it's still solid. Any good technical hands out there offering insight will be welcome..
Thanks,
