Yep!!
they work great.

here's my favorite bobber setup....
Thillâ„¢ Pro Series Slip Bobber Floats - Unweighted | Bass Pro Shops


easy to watch the bright pink stopper crawl up to the bobber...
good indicator that a sac has hit your jig or shiner on the way down...

I fish in Lake Verret a bunch, and I use the JB Salter bream hooks all the time, love fishing for bream on the bottom.
I'll tie a bobber stopper about a couple of feet above the bream hook an wait for the stopper to move, then set the hook.
