what I have noticed is that things are done differently in different regions.
Here in Dubai we use braid for backing & mono / Fluorocarbon @ 10mtr to 25mtrs in front depending on the kind of fishing you are doing.
I use a FG knot, which is a simple knot with a tedious tying (Time consuming) routine. (This is not easy to tie on a boat). This is also one of the smoothest knots while spinning, but has a protocol to follow whilst tying, else it will slip.
The reason for using Mono/ fluoro ahead of the braid, is that it has more abraision resistance than Braid & also has some amount of stretch.
Braid will get cut very easily over a rough surface & has '0' stretch.
If you use braid agead of the mono, make sure that you replace the first 10 - 15mtrs of braid everytime you fish off the rocks. I'm sure you wouldnt want to lose that 1 giant fish that you might hook up.....then again you could always write about 'The one that got away'.
