so the next question is - direct tie to fly line (plus a touch of glue) or via a loop like a grays loop or similar.
Doesnt need a loop Ed. Use a tapered leader. Most tapered leaders you buy will come with loop already on. [If not tie a perfection loop on the leader]
And dont bother with the super glue. Its not needed, and corrodes your fly line after a while.
Arbor Knot dacron/backing to Reel.
Nail knot, backing, [dacron,] to fly line.
3 turn Surgeons/water knot, to connect leader to tippet
Try and buy a braided leader loop with a coloured rubber tube. [red] [The bit that slips over the braided leader, and onto the fly line]
It works as a strike indicator when your nymphing.

These vids will tell you everything you need to know about knots.
A few lessons, casting etc, off a local guide would be money well spent.
Kilnsey crags, near burnsall are not far from you, and give lessons
