I have used Dinsmores shot since I started FF, and have found them to be a pita to change for most of that time. I've tried the putty, it works well when it's warm but I do like it. I just recently started using plain old split shot you know ( god forbid) the kind that is used with spinning outfits. I wanted to use them for years but never did because I'm FF not spin fishing. ( besides I already had a bunch of the dinsmores )The ease of changing the shot weight to match the changing depth and current speed is fantastic, I wish I would have done this years ago. I himmed and hawed about it for a long time until a conversation I had with Joe H. I carry bb, b, and #7. Yea I know #7 is big, there are sections I fish where that and some bead heads get me where I want to be.
