Comments about JBL Pro Sling with Blue Coating 5/8" X 24" (16 mm x 610 mm) for JBL4D24-L (Lightning) Spear Gun:

The problem with JBL's standard black bands is that the wishbone breaks easily, way before the band does. I have had some of these bands for over a year now with alot of use and the wishbones have not broken yet. Much more durable than the standard bands

Appear to be same bands as the black ones but supposed to be more durable. I just started using them. The wishbones look about the same and that is the weakness of the jbl bands.
