I've often found it amazing how much the right strap can help.
Years ago when I was a young bull and that 14lb RD Artist wasn't the manhole cover it would feel like today, in those days Reunion Blues made guitar straps, and they made a fabulous leather one with the padding in three seam-to-seam rows across the strap, and I've never had a strap that took so much weight off my shoulders. Sold a bunch of 'em to wimpy guitar players moaning about the weight of their Les Pauls.
Not to start a fight or anything, but I've always considered statement such as "wide thick padded straps takes weight off the shoulder", or "My heavy weight basses suddenly feel like a breeze", to be not really true.
We all got different perceptions and opinions (and thank god for that!), but I think it needs to be said, that unless it's a magic strap made out of a unicorn's tail, no strap will reduce weight on the back or the shoulder. A wide strap will maybe spread the weight from one inch of the shoulder, to maybe five inch of the shoulder, on the surface, which might benefit the skin, for some, but the weight on the shoulder is identical. A few cross-straps that sits on both shoulders might reduce the weight on the one shoulder - but still not the back. I would say that a wide soft strap simply gives a softer landing on the shoulder, but the long run back and shoulder wear is identical.
That certain straps reduce weight is a myth that needs sorted out, so we can add it to this universal talkbass truth list:
-1 watt is 1 watt is 1 watt is 1 watt.
-Tone wood in an electric bass or guitar means jack.
-P basses sounds better with flats and torts
-Carrots is a gateway drug
-The Mothman is one helluva bass
-Wide straps doesn't reduce weight on the back or shoulder
