A big portion of the Marstom Tornados steering feel is the STIFF Carbon tiller cross bar. On my boat:

The carbon tiller crossbar is steering with 2 fingers.
The Aluminum/Carbon tiller crossbar is steering with 3 fingers
The old Aluminum tiller crossbar is steering with 1 hand.

(I have all 3 and tried them).

Is the F18 restricted to aluminum for the tiller cross bar?
