Re: Classical Guitar Strings
Well, whoever these people are probably don't know how to string it up properly or are using cheapo strings which do break! Common mistake is not enough loops on the top two strings at the bridge, so when you're tuning up they unravel - three loops is the way to go; G string two, and the bass strings can live with one, though I do two for all except the trebles, old habit:
At the tuning peg, best to have each treble string so that it wraps over itself and locks down (once is enough), preventing slippage, then loop it loosely through the peg hole a few times. On my guitar, I find that two-three wraps around the post is enough for all strings.
Also a good idea to run some pencil lead at the nut and saddle of the bass strings.
Often it depends on the kind of guitar you've got as to how it's going to sound with particular strings. My guitar is cedar/rosewood, so it's quite warm sounding, and the treble strings each have a particular quality to their timbre, which is quite a Spanish thing.
D'Addario Pro Arté seem to be the 'standard', if you will - very serviceable string, good longevity. I've used some Augustine Classics in the past but didn't like them much - wore out fast tonally. Galli, Savarez and La Bella are also good. My favourite Savarez set is with the wound trebles - very balanced and recommended for the G if you find it too tubby sounding (a problem on cheaper guitars), and basses settle quickly. Galli Carbon Genius are also a good treble set - translucent nylon. The La Bella set I've got now is similar to the D'Addarios.
People often mix trebles and basses from different sets too - I quite liked the combination of Savarez wound trebles and Pro Arté basses on my guitar.
