I love DR Rare
Been a fan of DR strings with my guitars and basses (acoustic and electric) for some fifteen years now. I had trouble finding the right strings for my mandolin that would deliver the sound I like and would also last for more than two weeks (I guess I tend to pick with lot of force on occasion).
Once I found that DR makes mandolin strings, I had very high expectations for them. And my expectations were met. The sound is nicely rough and warm on the low end and clear on higher notes. Strings stay in tune beautifully and have that sort of soft but heavy feel that I like with DR strings for other instruments. And they do last a lot longer than others that I've tried.
