I've used these strings for years now on my guitars that I alternate between E standard and dropped D. They sound great and feel great. A bit different, not necessarily in a negative way, from your regular slinkies or D'addarios. Very smooth. Only con I have experienced so far is that I have to take really good care of them or they will start to feel old quite fast. Luckily I take good care of my strings, so these are great!
