So, how do Fat Beams and Sunbeams sit between Hi-Beams and Lo-Riders? I'm kinda happy with my set of Hi-beams(45-105), but am interested in Fats and Suns if I buy that Thunderbird I have intended. It's factorystrings seem like nickel rounds, quite flexible(then again I haven't played many nickels so I can't tell if they are naturally more loose than SS). Anyways, those strings give the bass nice mid/lowmid thump which is nice for from blues to rock, but eventually I will have to replace them so should I put my money on Sunbeams, Fat Beams or perhaps something else? I'm interested on some bright flats(or grounds or compresseds) too, they could perhaps give nice tone, similar to nickel-rounds yet last much longer than your average rounds.
