The only bad/good thing is the logo. In twenty tosses it went out... and its a pity.
The first "mod" I did with the STB2 and Sofia was to carefully remove the logo stickers and place them on wax paper for storage.
I still can do that in almost all of them. As I am planning to buy more STB2, I'll ask Maurizio for replacements logos.
Yesterday I was using a lot the Gustavo Castro's string and is so thick to the new tip. The original Strummol 8 string works better. But I need a longer string for the two-tips Giulia.
Today I'll change the tip to STB2 for a previous model tip. Crown and body for new test. Only butterfly has been removed, still is so big and heavy.
