I have a couple of questions regarding furled thread leaders.

1) Can they be used for nymph fishing to a depth of three to five feet?

2) If you have a 6 foot furled leader and want a nine foot tapered to 7x, do you just loop to loop 3 feet of 7x tippet on or do you have to step down to 4 or 5x then to 7x?

3) What kind of floatant and cleaner do you use?
