It seems to be mostly just a TB thing about asking the weight when buying and selling.
because TB members are, on average,
at least ~10-15 years older than the real-world, bass-playing group. old(er) players don't have to prove 'stamina' as much as they have to prove competence and relevancy --- which some find easier to do with lighter axes.
Spitball with me. Throw out the first thing that comes to mind. I need to talk this out.

you're still a youngster (it's a relative term!

) but you're old enough that you're in for some surprises in the not-too-distant future! e.g., i played he-man (it's a relative term!

) until i was ~60 years old, playing a ~10 lb. ax. sometime in the past 10-12 years that MOR weight hit me like a ton of bricks: always sore, always a chore, always a little too heavy. i started looking at lighter-weight axes just so i could avoid that heavier one. you might not have that experience until you're 65, or 68, or 70....but you will have it! it's in the cards.
but, you're not there yet! get the ax because you're excited about the possibilities, play it until you're tired of it, mount it on the wall, or sell it when you're finished with it. hopefully, your physical/bones will keep you interested in the ax for many more years. but mark my words: the day will come when you prefer to gig with instruments that are built for comfort...and you'll be 72, still gigging, with a

-eating-grin on your face because you found a 6 1/2 lb. bass!
in the meantime: good luck, stay healthy!
