I use these strings for standard tuning in D, but that means I also have to purchase a single E string to complete the set for a 4 string. I buy the matching D'addario .120, which makes things prefect. The feel of these strings is great, you get the same bit and tone from EB, but I think I prefer these even more and you can't get a similar gauge with EB. I've also had the DR DDT strings, which didn't go very well for me at all. 2 packs of DR E strings snapped at the tuning head when tensioning the string. I would never use them again now I've found this almost perfect D'addario set.
