I agree. I think most people put entirely too much stock in the brand of jig they fish. Most jigs of the same type (football, finesse, widegap/flipping) are pretty much identical. They'll also typically be either using a Mustad or Gammie hook. The legal limit jigs that you linked look to have pretty much the same head as GMan's football jigs. The main difference is the hook brand and that the legal limit one looks like a wide gap.
So, if you buy one brand of jig and the hook bends out, get upset and buy another brand of jig that uses the same brand of hook then how did you help yourself?
Also, aren't you asking to hang up flipping heavy cover with a football head jig? What pound test mono were you using when you bent the hook? Did you have your drag tightened down all the way?
In summation find a jig that has the hook you want and that doesn't cost a ton of money and you'll be happy. Jigs are made to be lost so I don't want to go broke fishing them.
