Currently on newtone 12, 17, 22p, 32, 44, 56 thick hex cored in drop B and C# standard.
Second place to dunlop Heavycore 12-54, which sound pretty good (a little thin, but that can be beneficial in recording) but dont last very long, and third to Kerly Sinister 12-56, which sound good, last a long time but the 24p on the 3rd is a bit much and they're hard to get hold of.
Edit - I tried DDTs. I hated them. They sound mushy and boomy.
