This is why:

" Thread: TMC 16/0 White, I use this new thread for a couple reasons here. It has good strength and is quite small. It is very similar to the old Gudebrod 10/0 thread but with better strength and believe it or not, it seems even smaller to me. It lays flat and works wonderfully on small flies or flies that require a lot of thread work..."

I have probably tied over 2,ooo flies with this thread - neither the GG's Sheer, Veevus 16/0 or Euro thread (Benecchi) lay as flat or are as fine diameter as the TMC..."threw or gave it away"... indeed
