I love your blue sqwigle, treble clef ftw! That is the sickest sqwigle I have ever seen by far.
As for the thickness, I know that .de zumos are 4.2mm but since mine is a .us one I wasn't sure if it is exactly the same. I was guessing it was 5mm but now when putting it up to other glass I have that is 5mm...I could definitely see that mine is 4.2mm too.
Sorry for the confusion, I'm too used to seeing 5mm RooRs I guess lol (the last two I have gotten are 5mm).
