Two or three inspectable options for this job. Failure notes are the compromises, not decoration.
Surgeon’s Loop, Perfection Loop and Kryston Non-Slip Loop fit this job too closely for the model to separate. The order is not a verdict — choose on the failure notes below.
Same rules. Switch knots without running it again — hold the trade-offs side by side.

Surgeon’s Loop
Line → loop (fixed end loop) · Monofilament
no field conditions declared
Relative ordering from weighted judgement. Not a retention figure, not a probability, not measured.
answer confidence low
- ·Level with Perfection Loop on weighted field fit (Strong). It is printed first on a faster retie (instant against fast) — not because it fits better
- ·End loop that is tied quickly
- ·Cold hands
- ·Strong connection-job fit (86)
- →Double overhand on bight; even seat
- →Tension profile: low. Slip sensitivity: low.
- →Failure-sensitive stage: bight formation
- →Failure-sensitive stage: pass count
- !Seated on the standing line alone, leaving the tag side loose so the tag pulls back inside
- !Tag trimmed before the knot fully closed, leaving it loose
- !Strands of the double crossed over each other inside the knot
- !Loop changes size under a test pull, showing the knot has not seated
Perfection Loop Strong
Surgeon’s Loop leads on retie speed (95 vs 84) and field tieability (85 vs 78). Perfection Loop still holds an edge on connection-job fit and finished profile.

You have a knot to tie. Field Ops turns that into a trip: travel, timing, what to pack, and what is still unchecked. The link carries the connection, the knot, the lines and the tying conditions across, plus whatever the tools before this one worked out, so none of it gets typed twice.
Take this to Field Ops Desk →No coordinates travel on this link, and it is checkable — everything on it is written into the address, so you can read it before you press it.
When this family fails, it fails as these. The recovered end still outranks the name.
A loop that stays the size you made, with a return that cannot cinch.
- !Loop cinched around the hardware — action is dead
- !Return path reversed, so it becomes a slip loop
- !Fluoro in a lock that only behaves on mono
- !Seated on the standing line alone, leaving the tag side loose so the tag pulls back inside
- !Tag trimmed before the knot fully closed, leaving it loose
- !Strands of the double crossed over each other inside the knot
- !Loop changes size under a test pull, showing the knot has not seated

What separated these options
1 · Surgeon’s Loop
2 · Perfection Loop
3 · Kryston Non-Slip Loop
4 · Homer Rhode Loop Knot
Ordered by how much each axis separated these options, not by its weight. A heavy axis every candidate scores the same on decided nothing. The bar is the score; the number beside the axis is what that axis was worth in this situation.
- Tie in the field, weight 0.9: Surgeon’s Loop 85, Perfection Loop 78, Kryston Non-Slip Loop 69, Homer Rhode Loop Knot 61. Highest: Surgeon’s Loop.
- Retie speed, weight 0.6: Surgeon’s Loop 95, Perfection Loop 84, Kryston Non-Slip Loop 84, Homer Rhode Loop Knot 68. Highest: Surgeon’s Loop.
- Job fit, weight 1.4: Surgeon’s Loop 86, Perfection Loop 96, Kryston Non-Slip Loop 90, Homer Rhode Loop Knot 92. Highest: Perfection Loop.
- Finished profile, weight 0.8: Surgeon’s Loop 70, Perfection Loop 85, Kryston Non-Slip Loop 72, Homer Rhode Loop Knot 72. Highest: Perfection Loop.
- Material, weight 1.2: Surgeon’s Loop 83, Perfection Loop 83, Kryston Non-Slip Loop 88, Homer Rhode Loop Knot 90. Highest: Homer Rhode Loop Knot.
- Under load, weight 1.2: Surgeon’s Loop 78, Perfection Loop 78, Kryston Non-Slip Loop 82, Homer Rhode Loop Knot 84. Highest: Homer Rhode Loop Knot.
- cold wet hand difficulty, weight 0.1: Surgeon’s Loop 92, Perfection Loop 78, Kryston Non-Slip Loop 69, Homer Rhode Loop Knot 61. Highest: Surgeon’s Loop.
- wind sensitivity, weight 0.1: Surgeon’s Loop 92, Perfection Loop 78, Kryston Non-Slip Loop 69, Homer Rhode Loop Knot 61. Highest: Surgeon’s Loop.
Every scored dimension, every surviving option, side by side. Weighted order — the top rows are the ones actually deciding this call.
What if the wind picks up and your hands go cold?
Surgeon’s Loop still leads. Field fit is Strong under that change (Strong here).
What if this connection must pass through the guides?
Recommendation switches to Perfection Loop — Strong field fit. Essentially level with Surgeon’s Loop on weighted field fit (Strong vs Strong). Treat them as the same answer and choose on the tradeoff
What if you had to rebuild it every twenty minutes?
Surgeon’s Loop still leads. Field fit is Strong under that change (Strong here).
What if you were tying this with unpracticed hands?
Recommendation switches to Perfection Loop — Strong field fit. Essentially level with Surgeon’s Loop on weighted field fit (Strong vs Strong). Treat them as the same answer and choose on the tradeoff
Where the catalogue went
Every connection in this discipline was checked against the job you set. This is what removed the ones you are not seeing — press a band to read them.
61 modelled · 51 ruled out · 10 survived · top 8 shown
A knot that fails more than one constraint is counted once, against the most fundamental one. Nothing here is a score — these are the checks a connection has to pass before it is ranked at all.
State the job.
We’ll say what holds.
The job
What is physically being joined.
Line and leader
The line decides what is even allowed.
Single-side job
This connection only needs a main line — no leader for this job. Switch to a two-sided join to declare both sides.
On the water
Only the conditions you tap count.
Leave these untapped and nothing is ruled out. Tap what you carry, and knots that need something else drop off.
Region
A starting guess for US water. You can still change every condition — it never forces a knot.
No region picked
Where you are
Water first, then how you are standing. You can still change the conditions.
Optional. Changes hands, stability and retie tempo — not the water chemistry.
