Given the minority of players that use low action, always take TB opinions on such a subject with a grain of salt, just like many opinions of fretless basses that might own a fretless and might play it sparingly.
Low action on a bass requires a very clean technique and disciplined technique. When it's all said and done, each individual bass will decide how low the action can go and not all basses are capable of the extremely low action that some of us desire. It pays to be able to know how to set your bass to maximum low action since you'll probably find that most techs don't know how. Moreover, you're best to set it to your own unique playing style.
The last time I took a bass to a shop for help on lowering the action, it came back with higher action, followed by many comments like, "basses don't sound good with the strings so low, you're not supposed to play up there, etc".
