the natural twist of the wing tends to
increase AOA, making the twist increase, etc...so you'll have to
make it stiffer than a straight or aft-swept wing.

And you might need a bit more than normal dihedral..............

IMHO the added weight needed for the stiff wing would be worth it for the added
visibility and cockpit room on a recreational aircraft.

Take a look at the Marske site for some ideas on forward swept wing design.

Graphlite rod is actually quite cost effective.
