10 or 12 yrs ago, I was talking to Bob Clouser Sr. about tippet material. He took a spool of Danville's Mono Tying Thread (smoke colored) from the case, put it in a tiny zip lock baggie with the tag end sticking out and said try it. He told me he's been using it for decades and had yet to find anything superior. It has virtually no memory, is strong and the smoke color almost disappears under water. I pretty much don't use anything else for my 5x-7x (comes as .006 or .004) tippets.
Oh yeah. It costs a buck for 100yds

.
Cheers
Marcus
