Dear classical guitarist, how do you guys determine the string tension to use? There's a lot type of strings on the shelves so how do you choose?

I used to believe Luthier Concert Gold strings are the best for my guitar(Admira Teresa) but a walkaround in Google tells me D`addario receive more fame and support from classical guitar sites. I even saw the statement "D'Addario Pro Arte best picked for Admira Teresa". So I suspect is because I chose the wrong tension string of D`addario that's why It doesn't sound nice on my guitar. I plan to give D`addario another try, (since it's so hard to find Luthier strings in msia) So how to know which string tension should I choose for my guitar? Also another factor to consider is the bass strings, should it be silver or bronze? Thx

hmm so hard tension or medium tension string better?

is hard tension produce louder sound? or... does it matter choosing what type of tension lol =P
