I haven't tried another time yet (it will be my 4th...), but I'll take your advice for sure! And I'll post some pics too!
Terri, I have to say that I don't like the Smoke Invisible Thread (SIT) very much... in my opinion it is not thinner than 0,12 mm fishing line I usally use, but it seems more soft. As a risult I find it is almost impossible to slip inside a turnbuckle to form a loop. As a note I should add that I am using 0,4mm brass tubing as turnbuckle and I am sure I did not cut them properly which led to some pinching that could also have a negative impact on the loops. But, TA-DAH!, after returnig to the fishing line it actually went better !
So... ehm... maybe it is better for me to leave SIT to girls!
Now, after this critique, I pray mercy to the court in hope for a mild sentence!!

Ciao
