Might be nice. A Kayfun 3.1 on top of an iTaste 134 is a heavy combo. Or a Kayfun 3.1 on top of just about anything. Or even a Kayfun all by itself, for that matter. Especially if you are using the stainless section instead of the clear.
But, I ain't no wimp. I can hack it. If I'm wearing a wrist brace, that is.
I'd think Titanium would be hella expensive.
