I have been converted to pure nickel strings since first trying them some years ago. The warm, vintage sound that pure nickel strings (not nickel coated) produce is amazing and it was a real revelation for me and I now use pure nickel strings in all my guitars
The DR Pure Blues are absolutely great strings, one of the best sets of pure nickel strings that I have tried. I often use Fender's pure nickel strings as well, simply because they are cheaper, but the DR are just as good if not better. They last a considerable amount of time with casual use (I only play at home) and they retain their brightness for quite a while before becoming duller. The one thing I would say is that they feel rather stiffer than other strings of similar gauge, so if you are used to playing with stings of a particular gauge, you may want to start one gauge lower with these. I have read some reviews recently that suggest the quality has deteriorated and breakage is a common occurrence, but I have not found this to be the case. Then again I only have one tremolo-equipped guitar, so this has never been an issue for me anyway.
