[QUOTE]The weight difference between steel and Ti is about .25 of a lb

Sorry thylacine, the engineer in me asks - is a lb of steel .25 heavier than a lb of Ti? (GRIN)
I believe you mean weight density, if so I believe you are in error. Ti is about half as light.
Thus an equal volume of steel = twice as heavy as an equal volume of Ti, at least Archimedes would say so. And I bet he would have chosen a litespeed!
