i picked up 6 of these at BPS today. They are sold in packs of two. I hope they work as well as yours. Looks like it has half the weight of yours.

Thats awesome. I will have to look for those. All you need now is the correct weight jig to stand the float upright.
WalMart has them, too.
You need to modify the bobber. Weight needs to be mid-float, otherwise you will miss uprising bites (aka lift bites). Here is a video showing how to modify. YouTube
I like to use a float thats matched to the jig weight any up hit is easily identified.
