This is the first time in a long time that I buy pure nickel strings and I do like these strings quite a lot. I usually play with stainless steel strings but these have a nice, soft feeling to them. They sound as they should and the roller wounded feature makes for a nice feeling. I may be imagining but they fell maybe slighty stiffer than regular strings. It's nothing handicapping about them at all and it might just be and illusion of comparing them to the 0.9's set I have on my other strat.
Something I had forgot about nickel strings is that the finger tips get stained after a while of heavy playing. Not a big issue, but just something I thought about.
