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.
A bight in the standing line, overhand through the bight, loop stays open under load.

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
Strong for the job you described. Next: Perfection Loop, strong.
A relative ordering from weighted judgement, not a strength figure.
No published break test, and the percentage would in any case need to say whether it is of the doubled loop or of the single line it is formed from — no source we read makes that distinction.
Nothing in the job you set pulls two of its needs against each other.
Fewer than three answers given, or this knot has no connection model behind it yet. More answers is what raises it.
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
- ·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
- !Bulkier than perfection
- !Not ideal: When the absolute smallest loop knot is required
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 →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

Same failure class, different geometry. Open the plates — Diagnose still starts from the symptom.

01Surgeon’s Loop
StrongSurgeon’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.
A standing loop locked above so the loop stays open under load.
02Perfection Loop
StrongCompact fixed end loop
Loose overhand, tag through the eye and back through the overhand twice; the box slid to size a fixed loop for heavy mono.
03Kryston Non-Slip Loop
StrongDocumented job from Hook the Horizon library
Overhand in the standing line, tag through hardware and back, wraps leaving an open loop.
04Homer Rhode Loop Knot
GoodDocumented job from Hook the Horizon library
A loop with an overhand sling wrap that locks the loop open — a fixed terminal loop.

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.

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

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.

We’ll say what holds.

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.
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.
