La Bella Vivace MT

I had a new guitar and had strung it with La Bella 2000 light for its first stringing. A good result but, sustain seemed weak.
I then tried Vivace Medium tension. There is a lot of stretch in these strings and they took a while to settle down, The 1st string is thin and seemed to need a fairly high tension. There is very good sustain and richness to the tone and a good evenness in response, A very good response to harmonics. Not sure that they are right for this guitar as there is not the distinction in the notes that I would like but I find La Bella normally offer very good strings.

don't remember except that the trebles had a lot of tension

Vacuum packing sound similar to the popular brands (e.g. Savarez).
