Red snapper and grouper can occupy the same offshore structure, but the tackle problem changes with presentation, depth, current and how quickly the fish must be stopped. A natural-bait bottom rig, a fast vertical jig and a pitch bait are not interchangeable rod jobs.
Natural bait around bottom structure
Reefs, wrecks, ledges, hard bottom and platforms concentrate bait and predators. Natural baits can be placed directly in those zones and held there. The system must control enough sinker to reach and remain in the strike zone while retaining power to move a fish away from structure. Red snapper may suspend above structure; grouper often create an immediate extraction problem because a hooked fish can turn back toward cover. That increases the importance of drag, leader abrasion resistance and low-end rod power.
A medium saltwater spinning build can be legitimate for appropriate snapper/bottom-fishing duty, but saltwater "Medium" is not equivalent to a freshwater bass-rod Medium. Power labels only make sense inside the blank family and its line/load design.
Vertical jigging
Fast vertical jigging is an active system. Metal jigs are dropped to target depth and worked with coordinated rod lifts and reel turns. Useful jig weight is driven by depth, current and drift because the bait must remain controllable and reasonably vertical. The source system centers roughly 100--300 gram jigs, rods around 5'6"--6'6" in medium-heavy to heavy classes, compact conventional reels, 30--50-pound braid and 40--80-pound fluorocarbon leaders. Those numbers show why this is specialty offshore tackle rather than a bass rod with heavier line.
Electronics and boat control matter because fish may suspend above the reef. If line scopes badly away from the boat, jig control deteriorates. Increase jig weight, improve boat position, or change the drift before assuming the fish are unwilling to bite.
Fish-fighting requirement
With grouper and larger snapper around hard structure, pressure has to come on quickly. The rod must load enough to keep steady pressure without folding under the fish, and the reel needs useful drag and line capacity. Short jigging rods reduce the lever the fish has against the angler and keep the system compact during repetitive vertical work. A longer pitch rod solves a different problem: presenting a bait away from the boat to a visible or approaching fish.
Pitch-bait systems
An offshore pitch rod can be around seven feet with a moderate-fast action and line class appropriate to the target. The progressive action helps the blank transition into load and protect line when an aggressive fish surges. Pitching a bait or modest bucktail is not the same job as repeatedly working a 200--300 gram vertical jig, and neither is the same as dropping a heavy bottom rig.
TCR routing
There is no standard Core Series rod that should be represented as TCR's red-snapper/grouper offshore system. The L904 has verified inshore/nearshore, live-bait and jig applications, but that does not establish it as a substitute for purpose-built reef, grouper, heavy-bottom or vertical-jigging tackle. True offshore territory is a custom-build lane.
For a TCR custom consultation, the useful inputs are target species and expected size, natural bait versus vertical jig versus pitch bait, jig/sinker weight, depth, current, structure type, braid and leader class, spinning versus conventional preference, and fighting style. Those requirements determine blank family and line class before grips, guides or appearance are selected.
Common failures
Choosing by species name alone is a mistake. So is confusing a freshwater power label with an offshore line-class rod. Current can also transform the required system as depth increases. Finally, excessive rod length can work against the angler in true vertical jigging even though length is useful for pitching.
The correct system is defined by presentation plus structure plus load plus fish control.
