I am wondering what people have thought of SIT strings that they've tried, especially the Power Steel and Rock Brights in Stainless varieties. I'm particularly wondering about users' thoughts on set to set and string to string consistency, length of life, etc. I've been using them for a few months now and have started to take note of an issue or two, but I do very much enjoy the strings I've purchased. Without going into detail just yet and possibly "leading the jury", I'm curious to know about others' experience. So, what do you think?
