I´ve tried many different strings during several years and DR are among my favourites (depends on the bass I´m playing). I´ve generally used Lo Riders or Hi Beams and although I like them, they feel a bit tight regarding tensión (mainly Hi Beams). Yesterday I tried Fat Beams for the first time. I´ve always considered gauge and material but didn´t know much about "roundcore" vs "hexcore". Read somewhere that Hexcore and more flexible and they certainly do. They retain the tone I like from DR, but at the same time demand less plucking hand attack. Anyone else felt this ?
