Hi Mike,
Here is a pic of 2 options (both are weedless):

The pic on the top is a 4" Croaker using a 28 degree 5.0 EWG jig hook and screw lock. The hook runs between the legs and then is skin hooked on the back of the frog. I've left it exposed so you can see it. The pro to this is your hookup ratio is extremely high. The con is the hook can come loose in weeds and you can only skin hook it so many times before you need a new bait.
The second pic is a 3.5" Croaker using a TroKar 4.0 EWG worm hook. You rig it like a normal Texas Rig and run the hook through the frog at the thinnest point in it's rear. The pro is your frog will last a long time and is more weedless than option 1. The con is it takes a little more skill to rig it perfect and my experience has been it can be a little harder to hookup if not rigged just right.
We sell everything you need for either setup
http://www.caneycreekmolds.com/Hooks-and-Eyes_c_28.html. Our prices are very aggressive (if you can find them cheaper anywhere let me know).
As far as sizing goes:
Between the legs: 3" Croaker - 3.0 EWG Jig Hook, 3.5" Croaker - 4.0 EWG Jig Hook, 4" Croaker - 5.0 EWG Jig Hook
Texas Rig: 3" Croaker - 2.0 EWG Jig Hook, 3.5" Croaker - 3.0 TroKar EWG Hook, 4" Croaker - 4.0 TroKar EWG Hook
As far as braid bending hooks, it can definitely happen. However, TroKar hooks are very strong and I believe will help greatly in this regard. Another trick that I learned Jig fishing with an ex-pro a couple years ago was to loosen your drag slightly. I really struggled with this, but he went on to explain throughout the day how a rod, reel, line, knot and hook all need to work together. Any one of these can be a week point if not setup to work as one. On a gorilla hook set your drag should give to prevent your rod or line from breaking. Your drag should still be tight enough that it doesn't give after the hook set unless it is a big fish making a run, but your reel is designed to give at a certain pressure, your rod is made to absorb a certain amount of pressure, etc... When they all work as one you can land really big fish without using a saltwater rig.
End of the day everyone has to do what works for them. None of us fish the same, use the same gear, etc. We need to adapt our style to our gear, fishing conditions and size of fish.
Hopefully this helps.
Tight lines!
