Tuning Levers

[Cy Shuster]

Thanks, Ron; I guess I did think titanium was stronger.  So it depends 
whether you measure by volume or by weight...

In the bigger picture, I like the fact that this is a strong shaft.  I 
really thought I might break the student lever I had; the flex in it scared 
me.
