One thing I would like to pass on. If you are using regular Mono or Fluoro (say 8 lb and lighter) like I do when deep nymphing, you might want to make a short BUTT section out of like 30 lb mono. The thinner line will cut the loop.
I make a small 6" butt section and put the thread loop in each end for deep numphing. It is not a worry if you are using regular or furled leaders, but I have read on here of people making there own leaders with LIGHTER butt section.
Just a heads up (from personal experience LOL)
It's getting into a different subject, but when I make a splice or loop in fly lines, I wrap the two bare cores with 10-12 wraps of thread, using a bobbin spinning around the axis, from one end to the other of the splice. I then coat the conjoined cores with crazy glue, let it dry, then start the bobbin spinning again, making consecutive wraps from end to end; then coat it with something waterproof and flexible, like clear nail hardener. A half-inch splice is stronger than 20 lb. line, according to my limited tests.
I've noticed that everytime I've used crazy glue around a loop or one of those braided splice sleeve after a while I have a hinge point that will eventually crack the flyline.
Now I use either softex or that ultraviolet setting knot glue.
I agree with FISHN50. On a fly line I don't like to use Super Glue or other products that gets completely hard. Pliobond has been used since the 50's and it is still a great product for making splices or loops in a fly line. I have heard that Goop is also very good. I have used a ton of Goop over the years but not on my fly line. Not that Goop isn't any good for fly lines but just because Pliobond works so well. Everybody use to carry Pilobond but lately it seems hard to find.

Frank's right about Pliobond. I have a tube I used in the 1970's for smoothing over knots, etc. which I recently re-discovered in an old vest pocket. It still flows from its tube as good as new - how many glues can you say that about? And the nail knots I covered over in the 1970's are still just as flexible, although I don't trust those 40-year-old lines for fishing now, just for practice casting.
ya know, I hear people talk about hinging all the time and I get what it is, but I don't think I have ever experienced it. I am sure I would know if I did, but anyway, I refuse to use Super Glue or Zap-A-Gap, for reasons mentioned.
Pliobond, or here I use WELD-BOND, dries rubbery. Even knot sense will get hard so that is out of the question, other than to mark my line at 30' with a dab. This is great for sinking lines.
Is this the Weldbond you are taking about? The home page states it is Highly Water Resistant but doesn't say anything about marine use. I would like it better if it was water proof or recommended for marine use. I will pick up a tube and give it a try. I have used it for gluing wood.

I have a hunch that something like the glue used to mend plastic beach balls etc would serve the same purpose more or less, would you agree?
This stuff is ao used to glue shoe soles so it' s quite flexible http://www.bison.net/upload/af993e0fc2c7dd2dc07b9e.pdf would do the trick.
Alternatively would a waterproof and flexible glue for mendig diving suits be an option, would anybody have experiences with that?
Would Pliobond be easily obtained on the east coast ?
(could ask a collegue who is an Sea-Angler to send me some to compare).
