La Bella 800L Jazz Black Nylon L

Use: jazz guitar

Pro: sound good, last a long time and have a very smooth sound

Cons: you really cannot cut these on the black (wound) section of the string, or it will unravel! If you avoid that, you are good though. One other thing - the heavy guage version of these are great (if your nut is cut for seriously big strings). The smaller guage though is so bendy you will apply the slightest pressure on them and go sharp, so proceed with caution!

Summary: a very good and interesting alternative to Thomasitk Infeld flat wounds for a smooth jazz tone
