Been a Nickelwound user for several years. Was looking for some heavy 5 strings kit (45-65-85-105-135 specifically) to use in standard tuning and didn't want to spend much for them, so I've given a try on these Stainless Steel ones and: Wow!!! Great bright sound, amazing time that lasts for a looong time. These strings have it all... Just takes a bit of getting used as they're kinda harsher than the NW ones, but once you get used to it, it just blows minds away. Won't consider changing sets now... Bottom line: Cheap, Great bright tone that lasts long. Delivery services from LotS are fast. Regards from Portugal.
