I used the double uni for 4 years with good success. Only twice did I break off on a fish, but I lost plenty of leaders when snagged on rocks and stumps. I have recently switched to the FG and it is awesome. I have yet to break off a leader. It has always broke off near the hook as it should. Super strong and thin for going through the eyes on your rod.
I use 30# braid and 20# flouro.
Set the hook first, ask questions later.
