These strings were bought in an attempt to broaden my horizon on string brands (I consistently go back to a different one), however they failed to convince me.
This doesn't make them bad. In fact they sounded pretty good at first, giving a well rounded sound suitable for many playing styles, including the heavier music I tend to gravitate to.
The slightly heavier bottom end is great for extra tension to help palm muted chugs, while maintaining easy fretting with the light top end.
Changing these strings was a bit of a faff though, at least in attempts to follow the instructions in the packet. DR ask you to add an extra crimp before snipping, as this apparently improves longevity of the string - weird how I haven't seen any other manufacturers ask for this. Now, here is the thing: If they actually lasted longer I would be up for it, but the strings needed replaced sooner than my preferred brand, which I have since gone back to.
I suppose if you are a regularly gigging musician, where replacing strings weekly is the norm anyway I can recommend these, as they do sound fine.
If you are like me, a hobbyist who wants to make stings last a while, possibly look somewhere else to find equally good (or better?) tone and less deterioration.
