I have never used a titanium hammer, but I do usually use a hammer lighter than anybody else does, a 16 for framing, a 13 for trim.
I believe that technique trumps weight.
Weight in a hammer trumps physiology. The result is damage to your body and then pain.
This is so often compounded by hopelessley bad design in hammers, hammers that give you no grip, so you have to cling to it hard enough to squeeze the blood from a stone - all day! Then there are hammers that transmit every vibration from the head into your hand. There are hammers that ring like a very high pitched bell with every stroke. And there are hammers that are designed unbalanced in such a way that every time you hit something with it, it transfers a torque to the handle which you hav e to absorb with your hand.
There's a lot of bad hammers around.
I also believe that good design and good materials can trump technique.
