Faulk titanium or carbon fiber?

[Don Mannino]

Or, you could just say what Charles Faulk told me - his Carbon Fiber lever 
is stiffer than his Titanium lever.

In my experience, it is also more rigid than my Schaff steel lever

I have used my Faulk carbon fiber lever for a few years now, and it is 
great.  Strongly recommended.
