Might be walking into dangerous subject.
The Bass string conspiracy. To keep you buying bass strings. My background.
A 62 year old bassment uneducated 9 year
So called bass player. I allways claim myself a newbie. But One thing i can claim is I have bought tons of strings all kinds. Looking for a deep warm tone at reasonable volume levels.
Reasonable in terms of living in apartment buildings and never having had people complain. Right now I looking for some new strings I have bought 2 packs of rotosound 77 flats with the little triangle that says warm sound. I have a set on my sterling ray and sounds beautiful. So now I want more strings
And reading all the manufacturers hype about how awesome there strings are. There is no comparisons except rotosound. Why is this?
I find it very bizarre that this is not the norm.
This has made be buy countless brands styles.
I would like to get a set of labella deep talking flats . Just because they chose to call the product that dont mean in regard to other strings there have a warm deep characteristic.
A little tag somewhere on product that sums up the sound style would be greatly appreciated. Is this sacred knowledge?
A big reason is probably that there is no absolute reference scale - it’s all relative and personal. What might be bright to you, is potentially dull to a slapper etc. So, companies might be reluctant to provide this comparison. But, that said, I am sure I have seen this on string packages from other manufacturers than Rotosound.

But, you probably knew that already!?
Finding the “perfect” string(s) is a tortuous and expensive journey 
So true and the sound is so dependent on a lot of factors other than strings, such as, the room you are in, are you plucking with your fingers or using a pick, where you are plucking between the bridge and neck, and one thing most people do not consider -Getting the amp elevated above the floor - just to name a few. 
Which bass, which amp, which strings? Down the rabbit hole we go.
Furthermore taste isn’t constant… The top bass-string-amp combo of today may sound boring a couple of months down the line.
BTW, I considered Rotosound flats to be my first choice on a 34". They sounded terrible on a 30". Completely uneven. But that 30" bass with LaBella’s is unbeatable. That’s why my 34" bass has D’Addario nickel rounds on it. That bass came with a set of rounds that must have been on that bass for a really long time, so long that the nickel is worn off in some spots and copper shows through. They are a different kind of “flats” and are great too.
^^^this.
Your taste changes back and forth. It gets triggered by many things like the current songs you like as well as a sudden AHA moments.
Another factor you also want to consider, some strings need to go through their break in period before they feel and sound great. Takes TI Jazz flats for example, it takes a few months of playing everyday to get it to feel great.
No copper. Bronze.
Fine. Copper with some crud added 
They spent 24 hours in alcohol.
So did I, but I don’t sound any better.
But you felt juuust fine.
I answered a question on a FB guitar page in regard to fret wear on the highest strings commenting that they should think about nickel rather than stainless steel strings.
It was pointed out to me that the highest strings aren’t wound.
I said oh yeah, I’m used to bass strings- did I just confirm a stereotype?
Me go back to bassment, play more bass and lick window
Damn it man, I own a guitar, doesn’t mean I should be expected to play it or know anything about it!
