If you're fine with playing heavier basses and
truly believe that they improve your tone, then by all means keep on playing them. I'm referring to the belief system started in the '70s by companies such as Alembec as well as the burgeoning aftermarket part companies which made a ton of money having people believe that every piece of hardware should be Brass for better tone (

) and that in general
all basses that are heavier/have more mass generate better tone than lighter/less mass basses, not *one specific bass* that weighs more -
I have
one bass that's fairly heavy and sounds amazing.
...but for a good deal of players here, we've moved to lighter-weight basses
because we believe that they resonate better and thus generate a better tone, or have moved to lighter-weight basses because of a physical issue (or both). I had a non-cancerous tumor removed at 21 from my Spinal Column @ T-7 to T-9 and have roughly half of the original bone there, along with scar tissue, to make up for it. I discovered that I would need a much lighter bass after my first jam session 4 months after my surgery, when after 5 hours playing I was stuck in bed the day after due to back pain and couldn't lift my arm above my shoulder.
Add to that that I'm a Person with a Disability from birth in the first place (Cerebral Palsy) and that a lighter bass would be better for me as a general rule, and I:
A) switched to lighter basses in general, and
B) switched to straps that are at least 3" across the shoulder (I think that's a good rule for bassists in general. I also use Neoprene straps as I feel the "give" the material has helps absorb movement and acts as a shock absorber, but that's my personal feeling)
It took me several years to find *my* basses but throughout the process weight was a major factor. I've ended up with Spector ReBop DLX EX & FM 4, 5 & 5 fretless (bolt-ons, Alder w/ Maple top) and Mike Lull Modern 4 & 5s (bolt-ons, Swamp Ash w/ Maple tops) that are all on the lighter side of basses, balance well, and still meet my needs in terms of tone. Along with a few other "specialty" basses (my Taylor AB-2 ABG, Dean Edge Hammer 10x 10-string, and MusicMan S.U.B. Sterling) that also meet my standards, I feel that I currently have as great a tone as I ever have
along with basses that put a bare minimum of strain on my back.
As posted before by several others, it's a personal issue related to the personal player. I've never seen a thread starting a "movement" regarding light basses (

) and on the other side I don't understand why some people brag that they play a heavy bass. Wowie wow wow to you.
