That seems to be a little extreme just to solve a neck dive problem. I own seven different basses and none of them give me a neck dive issue. I use an LM leather padded strap and have no problems with neck dive on any of them. They range from a Squire Affinity to a Kubicki, a Fender P and a J to a couple of NYC Sadowsky’s.
My straps probably grip my neck well without pulling on my shirt and I don’t even think about it so maybe a good strap is the key solution?
also, it could be that I’m just used to how it feels. My headless Kubicki neck definitely floats freely on my left hand but I don’t consider the others to be a significant issue.
