Hey again Isa.
I use just D'Addario Ultra Lights on my pro-line and they are pretty decent strings. If i had the money to do more expirimention though, i'd probbaly end up useing Fodera's. I must say, avoid Fender strings by any means possible, every set ive ever gotten has been complete trash. In the end, it boils down to what kind of tone, comfort and longevity you want to get out of the strings. Steel is generally brightest, and they last a good while to. My favourite steels are Rotosounds, I string my vintage basses with em, and my fretless to to get a good Jaco tone. Enrie Ball and GHS are good steels to. Nickle strings are my favourites, they are a tad warmer than steel and respond better to strong magnetic pickups (like a $$). My favourite nickles are D'Addarios, DRs and Foderas. Theres also Half wound or Pressure wound. These strings are good for studio situations or for people that need a good pallette of tones, they have moderate brightness and a very smooth feel. D'addarios and Rotosounds are incredible in that department. Then theres flatwounds, my least favourite, which i have nicknamed tone killers. Very flat, very warm. D'addario chromes, Rotosounds, GHS, and Thomastik Infeld are good names. Finnaly, theres taper wound strings. They are very boomy and have a very unique studio charecter to them. La Bellas are my favourite here, and Rotosound TruBass strings are allright to. I dont know much about coated strings beside the fact that I didnt like elixers and that DR peacock blues were some of the best strings ive ever played.
If i were you, id save like 200 bucks and buy every set of strings you can get your hands on, and just take a real lab approch to getting comfortable with strings. If your low on cash, Try Rotosound 66's, D'Addario Nickles, D'Addario Half Wound, Thomastik Infeld flats or Roto Flats, La Bella Taperwound and DR or Elixer Coated strings.
I hope you find a good set of strings for your std, worst comes to worse just grab some warwicks. Drop a line if you have anyother questions.
