Yep, that's the point I alluded to in my first post above by pointing out that the thin shim is not conducive to providing much thermal conduction resistance in the first place (i.e. since the "L" is so small in basic conduction equation) and why the two contact resistances introduced in the conduction path are significant relative to the conduction resistance of the metal. Ti likely became a marketing gimmick to some extent early on about 20 years back now. I don't think it's worth the expense of Ti versus a cheaper stainless steel with conductivity in the same range depending on the alloying.
