Tying thread conversion!!!

[PigsEye]

I know this has been asked several times before, but i was unable to find it in the archives...i have some spools of ultra thread that i bought at gander when they got rid of their fly tying stuff (really unhappy about that) and i need to know the conversion.

The thread is 210 and 140...is that 6/0?

I thought that the local Gander had discontinued tying stuff. I was wrong, they had moved it back into one of the aisles. Look around, your Gander may still have tying material.
