a braid to monofilament knot

i was going through old photo files and found this unusual knot taken years ago from a Berkley catalogue. unusual for us in the fly fishing world because it’s for connecting braided lines, so popular in the spin fishing world to monofilament, nylon, copolymer or fluorocarbon.
however, a lot of fly fishers are experimenting and using braids as the main core of their leaders, specially in the European nymphing methods as braids don’t stretch, leading to a higher sensitivity in detecting strikes, a very important bonus for this type of nymphing.
being braided, they can not form a ‘memory’ coil and they also are much-much stronger than any mono for the same given diameter.
knot-wise,  braids slip like crazy compared to monofilaments because of their structure and coatings and they require special knots.
in the case of mixing materials like we’re doing here, we also want to be careful to not destroy one’s resistance with the other by having the stronger non-stretching braid dig into the softer flexible mono.

the Stren Knot below is pretty self-explanatory, notice (and hopefully keep in mind for later use on the water) that the mono knot is tied like a 5-turn Duncan (Uni) knot and the braid like an 11-turn Improved Clinch.
easy and strong, give this a try if you’re experimenting with braids.
