Bob on the Ridgeback you can't use a release on the weight it's self.It will efect the tracking of the weight.You could use the blacks on top of it.I also use a blacks release and rubber band.But I use the slider clip.Because of my Temp probe.I use a scottys cable stop in the middle of the clip and it keeps it from sliding up and down the cable. I'm not sure about the sharks I will ask a charter captain I know who uses them and get back to you.
Bob I have the yellow colored one but I am thinking of painting it black like all the other weights I have.I'm not sure yet if you are going to the gathering I could bring it with me so you could see it if you want.just let me know.
