Bun,
I bought the 6x VMC's in size's #4, #2 and #1 for jack and barra lures, though I found at times the heavy wire of these hooks added too much weight to the whole lure and killed the action.
Once up to 120mm in length, I just got rid of the belly treble and it didn't stuff the action up on these size lures.
Travis,
When I was pegging poppers all over BreakSea Spit, the most commonly used popper was a 150mm BillsBug.
These things got swallowed all the time!
I remember seeing a photo of Tim Baker with his arm down the throat of a massive GT up to his shoulder.
If you don't know Tim, he's 6'3 and a damn fit bloke, so it was a looooooong way in!
Since the lures ended up on the inside of the mouth, the Gamakatsu Treble 16 5/0's we were using held together most times.
Jaw hookups were where hooks got twisted a fair bit more, which is one reason why we looked for stronger hooks.
Aaron.
