Size the sleeve to the measured 1.18 mm diameter, not just the pound-test. Start by bench-testing a \u003cstrong\u003eDiamond Silver Lock L aluminum sleeve at 1.3 mm\u003c\/strong\u003e. Its published leader range is 1.10–1.20 mm, and the longer body gives you more bearing surface. For a shorter, more compact rig, test the \u003cstrong\u003eDiamond Mini-Lock LL at 1.3 mm\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eThe sleeve should thread cleanly without forcing the leader through and should not feel loose before compression. Match it to the correct crimping-tool cavity, compress evenly, keep the sleeve ends clean, and pull-test the complete rig before fishing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDeckhand note:\u003c\/strong\u003e Sleeve fit matters more than pound-test. If it takes force to thread, size up. If the line swims inside the sleeve before crimping, size down.
