I fear I'm not helping here, but whatever you choose today, and when the DB bug bites you, you will end up trying all of the afore mentioned strings plus many more before you settled on your "holy grail" string.... For a couple of months, then you'll try some more and finally settle on the real "holy grail" string for 6 months.... Then you'll suffer some more as you hear a great bassist sounding divine on a type of string, which you will rush to buy, only to discover you sound crap on it... And this will go round in circles... Your initial resolution to get cheap strings will turn into a twisted vortex whereby you start thinking that £200 for a set of strings is a bargain... Sounds like torture, but it's great fun: you will have a blast!
