Ok, thought Id share. I saw a new sealed set of Alice chrome flats for upright bass, $32 shipped. I mean, at that price, I had to try them. They were sealed, new shiny and tight windings, look of good quality compared to the typical makers. Installed and found they settled in quickly. They play well, fifths are good, finish works with a bow, etc. I will say, the tone is different than Helicore hybrids with more sustain, more electric like, and more crispy highs, which isnt as desirable to me, but manageable. Too early to know if they will last or not, but they note like new strings compared to the old Helicore Hybrids they replaced. Short story, easily usable for a super low price, unmatcheable. PS - these are lighter and lower tension than Helicore mediums.
Also, gently used clean strings are an option, from those who change every 6 to 12 months.
