Yes. Lighter gauge strings in many cases give you a clearer overall tone, afford more dynamics depending on touch, and in some cases can help a bass 'speak' and feel better. A lot depends on the bass, and a lot depends on the player. I have always used light gauge strings as a general rule, regardless of core type. Hex core feel stiffer in general, while round core in general feel looser and more pliable. I've settled in the last few years on DR Sunbeams in a light gauge (round core), but also have some Lakland/GHS Custom Wounds in a light gauge that are hex core. I've never bought into the myth that heavier strings make a bass sound 'bigger'.... a lesson I learned to a major degree on double bass. There are some bodybuilders in the double bass world who swear by the heaviest, stiffest gauge steel strings imaginable... but those choked the life out of my bass and make it a chore to play. I switched to lighter steel strings (braided core), and then for the past 18 years or so I've played nothing but synthetic core strings of some sort. Lighter tension strings sound and feel better and don't rip my hands up after a 3 hour set. That's true on electric or double bass.
