Hi All,
I've searched the archives to find out how size A thread compares to 6/0 fly tying thread, but couldn't find what I was looking for. Perhaps I wasn't asking the right question. I would appreciate any help in being able to know the difference. I've been using A size to wrap my guides and tie my flies. I don't think the fish really care. The flies seem to hold together. Maybe the difference is metaphorical!
Thank you for your response.

6/0 < 4/0 < #100 < #50 ~ = size A.

6/0 is very small diameter thread.

Thanks Erik,
I suspected there wasn't much of a difference.

It's on another site

Steve,

I think you missed Erik's point.

6/0 is very much, a heck of a lot, amazingly, a great deal, obviously and unmistakably SMALLER than size 'A' rod wrapping thread.

There is a HUGE difference between the two.

6/0 is thin, like kite string where Size 'A' is thick, like 1/2 in rope.

Size 'A' thread is way to big for 99% of fly tying chores. Even guys tying 5/0 saltwater flies don't use a thread that thick.

A few oddball patterns call for it, often for a body material, but seldom is it used as the tying thread itself....

There are many reasons why it's not the best choice, but the one that stands out the most is thread bulk. You can't take too many wraps with 'A' thread before you have 'way too much' there.

Steve;
You can easily figure out the difference for yourself. Take a hook of any size and wrap it to the bend with each size thread and count the number of turns it takes you to get there.
