ATM: Magnesium truss tubes?

[bagheera@worldnet.att.net]

Hey all..
    I'm considering any and all options to build a 10" airline/backpack
-portable truss tube scope.  I've seen many great ideas here on
the list, that I would like to try and incorporate.  One of my bigger
concerns is weight.  A friend suggested using magnesium tubing.  Anyone
know how it compares in weight to aluminum?  How sturdy is it?  Does it
flex much?  Is this a viable alternative to aluminum?  Any thoughts here
are welcome.   thanx.
