Ultrahigh molecular-weight polyethylene — the generic name for both Honeywell Spectra and DSM Dyneema fiber — has been used to make thin, strong fishing line for two decades. "Braid gives you greater capacity, more strength, better longevity and increases versatility," says Bryce Poyer, owner of White Water Outfitters on eastern Long Island, New York. "If you change monofilament like you should, braid backing saves money over time." Here is how Poyer connects a mono top shot to braid backing much like a wind-on leader.

Start with about 6 feet of hollow-core braid not quite double the working strength of the monofilament. Poyer chose 100-pound Spectra braid for 60-pound mono. He says 80-pound braid would have been to thin to conveniently splice, and anything over 130-pound braid might be too loose.

Using a splicing needle, insert one end of the braid roughly into the middle of the 6-foot section, threading it toward the opposite end of the braid.Capt. Vincent Daniello

For top shot splices where there is no reason to limit length, Poyer likes that doubled section of braid to be between 24 and 30 inches long.Capt. Vincent Daniello

At this point, with just a small loop at one end of the splice, Poyer likes the inner section of braid to be about 4 inches longer than the outer section.Capt. Vincent Daniello

Insert something in that loop so it can't retract inside the outer braid — a line leveler for spooling spinning reels is used here. Scrunch up the outer braid up out of the way. Insert the mono top shot into a hollow splicing needle, and thread that needle up toward the loop in the braid.Capt. Vincent Daniello

Poke the splicing needle out of the braid close to the outer braid that is scrunched up out of the way.Capt. Vincent Daniello

If it's difficult to keep the mono locked inside the needle, touch the DaHo needle with flame to lock the monofilament inside the needle before threading it through the braid. Touch it again with flame to release it — shown here — and then trim off that end.Capt. Vincent Daniello

Pull several inches of mono out of the braid, remove the needle, and cut back any questionable monofilament. Rough up the end 12 inches of mono with 120- to 180-grit sandpaper.Capt. Vincent Daniello

Taper the last half inch of mono almost to a point. "That transition from thin braid to thicker mono creates a hard spot. If it breaks, it's always right there, where the monofilament ends," Poyer says. "The smoother you make that transition, the stronger the splice."Capt. Vincent Daniello

Pull the end of the monofilament back inside the braid. At this point, the monofilament is snuggly inside of one layer of braid.Capt. Vincent Daniello

Gently work the second, outer layer of braid over the inner layer and monofilament.Capt. Vincent Daniello

Adjust the loop size so the outer layer of braid is about 1/4-inch longer than the inner layer of braid to help taper the final splice.Capt. Vincent Daniello

At this point, Poyer locks the braid and mono into a serving jig — he uses a couple of woodworking clamps bolted to his workbench.Capt. Vincent Daniello

Poyer serves with braid slightly heavier than the maximum drag he expects that top shot to be subjected to — In this case, since the top shot is 60-pound test mono, he assumes it won't see more than 30 pounds of drag, so he serves with 40-pound spectra braid.

Starts the serving atop the braid about a half inch from the braid to mono junction, working up the braid onto the mono. Lay a few inches of serving braid parallel to the mono and wrap tightly over the top of it five or six turns.Capt. Vincent Daniello

Pull the tag end of that serving braid tight and trim it off with about a quarter of an inch remaining, and then continue to serve tightly over that tag end.Capt. Vincent Daniello

Poyer's serving tool sells for about $15 at bow-hunting outlets.

Cover about about 2 inches of mono, and then turn the serving back over itself, wrapping a second layer of serving braid over the top of his first layer.Capt. Vincent Daniello

Continue over the entire serve and then over the braid about a half inch past the original starting point.Capt. Vincent Daniello

Lay a loop of braid parallel to the monofilament, and then serve over the top of that loop until back to the original starting point, so the entire length of serving is two layers thick, but no more than two layers thick.Capt. Vincent Daniello

Cut the serving braid from its spool and tuck it through that loop of braid.Capt. Vincent Daniello

Pull the opposite end of the looped braid so the final tag end of the serving braid slips beneath the final section just served.Capt. Vincent Daniello

Poyer trims the end and finishes off with two-part glue from Jerry Brown Industries, first brushing on the activator and then applying the glue.Capt. Vincent Daniello

Poyer ties a Bimini twist in solid-braid backing. Hollow braid is spliced into a loop using the "inside-out" splice shown on DaHo's website.Capt. Vincent Daniello

Make sure that loop in the backing will fit over the spool of top-shot monofilament to form a cat's paw.Capt. Vincent Daniello

Colored braid mushrooms nicely with a flame to secure knot tails. White (uncolored) braid doesn't, since it doesn't include the wax-like color coating. Poyer prefers white braid to serve with, and even chooses white braid for the mono splice if he can, since that waxy coating does make braid a little more slippery and a bit harder to splice.Capt.
