Metalliferous question

I want to make some L shaped attachments to secure fish hooks to so that
they point upwards, hooking the fish in the roof of the mouth.  Lead head
jigs do very well for this, and they make it easy to take the hook out and
release the fish so that it survives.  I also want to make some T shaped
standoffs for crappie hooks that will keep the hook away from the downline
and tangling.

What do you think would work?  Piano wire?  Guitar strings?  Just go get a
couple and try it?  Is there any special name or type of VERY thin rods that
keep their springiness, yet allow bending?  What is the smallest SS Tig rod
available?

BTW, a friend of mine's Dad was the one who invented and patented the
rotating bass hook.  He was from Oklahoma.  But danged if I can pull his
name out of my grey matter.  The hooks were known for years by his name,
"(insert his real name here) hooks", and Eagle Claw used the term for years
after they got the patent, and the name became generic to the twisting bass
hook that would hook up with more bass.  I think she still gets royalty
checks.
