Apologies for this newbie question, but I've just begun playing upright bass and have a new instrument I'm hoping to breath some life into. I've been recommended to change the nasty factory strings to either Helicore Hybrids or Thomastik Spirocore. Here's some info about my style and instrument: - It's a Stentor Student I (currently not set up) - I'll probably be playing pizzicato but also arco about 30% of the time. - I'm a huge jazz & blues fan and need something with a bit more body than the dull strings I currently have on. Any advice, suggestions or alternative recommendations on my choice?
