For me were of very good strings.
I have used one year and not fart FREQUENTLY (every two months I changed) ...
Note that I played 2 hours a day and sometimes I "Burin" ...
I play with a lot of mtal and are suitable for me. although preferred for small Ernie Ball ... have strings that ensures better now when solo rhythm!
even given in drop c it takes too much curl but no good will be taking a higher veiled welcome =)
