DR DDTs are perfect or Type O NegativeLove the DR DDTs myself. Use them for my drop tuned basses. Everything else gets Ernie Ball Regular Slinkys. Tried the Ernie Ball Power Slinkys and the tension just killed me. Bought a set of D'Addario Pro Steels to try a steel string and they are not my favorite. I'll play the life out of them but probably won't buy any more.
