I bought these in the hope of getting rid of the sensation of the strings being really floppy in D drop C or C# and in that all my expectations was fulfilled. What a difference! It's a whole different sensation picking the strings now. The previous set of strings was the stock strings and I'm not sure the gauge of those but I expect they were fairly standard strings. These are really nice and heavy and I like them a lot.
Only drawback is that with these you really have to put in a lot more force into your hammer-ons and pull-offs. The first time I did a hammer-on I couldn't even hear it! So if you're used to playing with standard gauge strings you might have some re-learning to do when buying these strings. But if you're in the habit of playing with a down-tuned guitar I heartily recommend them. They seem to keep the tuning quite good for a new set of strings but I haven't had them long enough to see how they keep up in the long run. They seem to be quality strings though so I don't expect them to give me any grief in that department.
Be aware though that particularly string 5 and 6 are really thick and might a bit rough on your fingertips depending on how tough your calluses are. Long slides in particular is... ouch!
These were one of the first strings I went for outside of EB's and D'Addario. Honestly, I think I prefer DR's DDT sets now. Some nice different gauges, I use these mostly in Drop B on a short-scale instrument. I find them a tiny bit loose for going a bit lower, but then I like my strings pretty tight. Props to DR for making some amazing strings, there's just something about these that I can't resist!
