---From the tri-gear manual, 30 May 1998 edition, page 29-12:
Remember that the bungee does not provide the nose gear springing, the
flexibility of the leg does
this. The bungee is to allow a momentary overload to take place without
over-stressing the anchor
point.
If this is the purpose of the bungee, any stress that is sufficient to break
the bungee AND the factory specified safety cable is quite likely to over
stress the anchor point. Ergo, it is probably not a good idea to add
strength to either, and in particular to strengthen the safety cable. The
energy dissipated by breaking the bungee might protect the anchor points
---From damage but I suppose that breaking the cable will definitely cause some
damage and breaking a thicker cable would cause even more damage. Any
landing bad enough to break either is likely to be expensive so I guess I'm
just quibbling about what pieces will need to be repaired.

On topic, I doubled the diameter of the safety cable, using plastic
coated comm'l cable. Yeah, I know, not aviation grade, but 4X the
area, as there has been breakage on hard landing I hear. The plastic
I figure will help prevent chafing of the frame, causing rust in
places you cannot inspect so easy. I also swaged on 2 ferrules for
extra safety.
