Don't fall for the double rubber hype. Most of the spearo's using them are gut shooters. I've put 15kg blue spot trout to sleep hundreds of times with a single 5/8th rubber. Use dynema as your bridle heaps better and shot placement is far more important than power. Exceptions are big palegics if your bent that way 😜
Where are you fishing what part of the gulf...and is that the name of the wreck. Man i love to eat amber jack. Im so gonna look up that site. I go out of destin mostly
Don't you worry about a Goliath taking the unattended fish? I had that happen to me with a large for me (40ish in) AJ on South Jack Wreck. took my stringer with it...
