Zebra I am not sure where you get the Ti is heavier than CF idea from, because of its strength you can use very thin wall Ti and when used like that it is no heavier than CF. Titanium is not a heavy metal at all, it has great strength and is lighter than steel. I have made LDC's in aluminum, carbon fiber and Titanium, when you take the finished weight of them after machining, the differences between them is negligible. Ti is expensive compared to the other 2 options that is why I stopped using it, plus it is a lot harder on your tooling than aluminum and harder to machine and get a nice finish, just my 2 cents for what it is worth, Neil.
