You know what it has to do. Here is how the pieces go together.

These are transparent form presets, not recommendations. Loading one fills the job fields below and nothing else. Every value stays visible and editable before the engine builds a rig.

• River · near-bottom driftModerate current, occasional bottom ticks, compact leader, low-to-moderate snag risk.Load and inspect →
• River · strong-current snaggy holdPushy river current, constant bottom contact, wood or rock present, and a deliberate weak link to the weight.Load and inspect →
• River · fly-line swingModerate flow, a presentation crossing the current under tension, little intended bottom contact, and a fly-line main system.Load and inspect →
• Stillwater · suspended holdOpen water, fixed depth target, no bottom contact, light movement.Load and inspect →
• Stillwater · near-bottom drop-shot jobVertical or short-cast work, bait held above bottom, occasional weight contact.Load and inspect →
• Ice · suspended jig through a holeStill water under ice, a direct vertical path, no intended bottom contact, and a presentation held well above the substrate.Load and inspect →
• Ice · current under the holeA vertical ice presentation where unseen current pushes the line off-plumb and occasional bottom contact is needed to verify depth.Load and inspect →
• Surf · bottom holdMoving water, constant bottom contact, long cast, low-to-moderate structure risk.Load and inspect →
• Surf · heavy sweep and long castStrong lateral sweep, constant bottom requirement, a long cast, and enough terminal mass that casting load becomes part of the rig design.Load and inspect →
• Surf · moving bottom crawlLight-to-moderate sweep, a presentation intentionally moving across the substrate, and contact that must stay informative without pinning the rig.Load and inspect →
• Inshore · current holdTide present, constant contact, moderate depth, some structure.Load and inspect →
• Inshore · shallow tidal driftShallow water, moderate tide, a presentation carried with the flow, and no intended bottom contact over mostly clean ground.Load and inspect →
• Inshore · vertical jig beside structureModerate depth, direct vertical work, occasional contact, strong current, and high abrasion or snag exposure beside hard structure.Load and inspect →
• Offshore · vertical dropDeep water, direct vertical path, bottom contact used as a reference rather than a drag.Load and inspect →
• Offshore · deep strong-current dropTriple-digit depth, strong current, a vertical drop that wants to sweep away from the boat, and occasional bottom verification rather than a drag.Load and inspect →
• Offshore · midwater vertical jigDeep open water, direct vertical jigging, no intended bottom contact, and a presentation held in the middle of the water column.Load and inspect →
• Flowing water · tight-line nymph jobFly line system, near-bottom drift, direct contact, moderate flow.Load and inspect →
• Stillwater · surface presentationNo bottom contact, no current requirement, presentation remains in the film or on top.Load and inspect →
