I have ordered my first bass, and need to specify the strings for it. I will be playing mostly orchestral music with the bow, and will be playing on a rather large bodied, hybrid bass. I will have some opportunities to play jazz with a trio. I have narrowed the decision to either the Oligatos, or the Jargar Mediums (though I have considered the Helicore Orchestra or Arco). The talk of the Oligato's slow response to the bow on the lower two strings, and the problems with uneven stretch bothers me. I understand the Jargars are also gutlike, even toned across the four strings, and are warm and sweet. All this sounds good to me, but how do they respond to the bow? Is it easier to get the two lower stings into motion on these strings? Do they have enough sustain to be passable for jazz? Thanks for your help.
