Propellars,

If you have not used the search function; may I suggest you do so. You will find lot's of info on the SR.

You fail to mention where you feel the weakness lies, whether it be in the actual wire or if you feel the wood is too soft, etc...

The stock wire supplied is definitely too flimsy, but not something some 1/8 music wire should not cure. Also suggest you add a reinforcement plate to sandwich the fixed portion of the canard assembly to the mounting plate.

If the wood appears to soft; some carbon fiber strips inlaid span wise should cure it's ails.
