Hi Paul, I certainly yield to Ron's expertise on the subject. A number of technicians have made the same suggestion in the past few years. My exclusion of the idea is simply based on practicality ... 1/2" titanium tubing stepped down to 3/8" on the end (to accept the threading) just doesn't exist, at least not on any sites I have visited. 1/2" titanium rod has worked well for me with no noticeable flexing. The only flexing I encounter regularly is that of a .282" tuning pin. Now a titanium tuning head .... there's a thought!
