Default Halfshafts for IRS: solid or tubular?
In doing some reading I have come 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 defferential to the wheels. I noticed some Fords, SPFs and quite a few others use SOLID halfshafts. Butlers and others with modified Salisbury units went with strong (thick-walled?) tubes. Which is preferable? SPF offers a stronger upgrade...but it's still solid. Any technical hands out there offering insight will be welcome.

Thanks,
