Hello Nicky,
It's all new to me too, I haven't been fly fishing long, I just stick with braided loops. Don't put too much superglue on though as it wicks through the braid and makes it stiff......just a dab will do. I also trim them down like L_muslibar has suggested as it makes them neater.
I have recently bought some Roman Moser loops and they are very good.....nice and neat. I think they are the best I've seen but a bit more expensive.
If you are feeling adventurous some lads like to "weld" a loop in the end of their lines. I've not tried this so cannot comment but it looks a good job. There are some good videos on you tube. Good luck.
Regards Ian
