I fish with braid to a modified albright to a top shot of mono and do not have problems. Your method is not flawed. That doesn't mean that your rig is not causing problems.
to troubleshoot your problem, forget the mono all together. I would tie a lead sinker of the right weight (pick the middle of the rod's load rating) to the braid and go to practice. Follow all of the advice on the thread.
Maybe find someone to work with you. I'd volunteer to go out fishing with you, but its a bit of a drive.
