Hey mate, search button will be your friend here, many a debate on what leader knot is best, from double uni to pr knots , as for leader strength that will also depend on what you'll be doing/species you'll target.

I'm sure few blokes can help you out, but give YouTube a crack for braid to leader knots, and search the previous articles, there is a wealth of knowledge

 Personally I run 80 lb on my 50lb set up, and around 3-4metres of it joined with an Fg knot I learnt from a tutorial on youtube

 if you do a YouTube search on 'nomad fg knot'  there is a good tutorial, easy to follow. 

 Awesome thanks guys.

I've googled it heaps but get a bit lost on what will work best.

I was thinking a 60lb or higher leader with maybe 3 or 4m but just wanted sure if that was going to be enough.  

Thanks again ! 

 if it's for bottom bouncing maybe go a bit heavier,  say 80lb or even 100lb for more abrasion resistance. You could always tie a bimini twist in the braid to make a section of double line and attach a wind on leader. This gives a very strong connection. Bimini looks complex but not to bad once you have a few goes. Youtube, a few beers and some spare braid to practice! 

I like to use a Bimini  to a gt knot is easy enough to do out on the boat if required an keeps the tag end facing down the line so it also casts well.  

Awesome I really appreciate the advice !

Cheers again !

 you Tube search will show you. There is one technique where you need only use your hands. No harder than learning the Bimi twist. 

The guys before have pretty much covered the basics, I found that the guys at Big Angry Fish have some great demonstrations on youtube that show how to tie knots.

I personally use the FG knot when setting up gear before I go out. If I have to replace the leader during a hot bite on the boat I find it takes me to long and I go back to using the improved Albright.

I have come up a while ago with a bit of a gadget made from some leftover timber as a frame, 2 small screws, a larger screw (to hang/clamp the leader roll on), and a swivel lock.
Make a loop in the leader ,hang it through the open swivel back to the screw on the other post, make the line tight and clamp the roll off.
Then tread the braid through the middle of the 2 strings of the leader and start winding the loops on.
When you have made enough loops up and back down, tread the braid back through the middle of the leader at the swivel and back onto it self, wet it and pull it tight.
Cut extra bits of and apply nail varnish if so desired.
This what it looks like.
And the knots do not fail!

 That's awesome what a great idea !

 The Albright knot is one of my favorites as is easy and compact to slide through the guides.

Went and got some 120lb Jinkai leader today and after 3 or 4 failed attempts I've seemed to got the Albright Knot sorted !

Seems to be super strong and really easy to tie ! Thanks again everyone !

 When pulling up your albright make sure to pull up on the tag end of the braid also.  I wrap it around my the nose of my split ring pliers. Then do all your pull ups again and then  give the whole knot a working. Tie the end of your leader to something or put a hook on and attatch to rail on your boat and bounce on it a number of times under as much pressure as possible.  If you dont do this the knot can sometimes unravell and fail.  Learn how to tie a binimi in your braid also. Its a lot easier than it looks.

if you are prepared to outlay 70-80 dollars on a quality bobbin this is a knot that is simple to tie with a little practice. You can easily do it whilst in a boat and has near on 100% strength and offers zero resistance going through the rod guides even very small eyes.  

surprised some of you guys are recommending some fairly advanced knots for someone just starting out with braid (PR & FG knots) to start out you need something easy, quick to tie and reliable. The Albright or "improved Albright" knot ticks these boxes and I still use it today. I only use an FG if chasing serious pelagics and need a long leader which can cast through the guides of my rod.

I would only advise using a mono leader if you are using lures or live baiting. If simply bottom bashing, pre-tie your rigs (whether paternoster, floaters ect.) and store in clip strip bags. join the braid to the mono rig with a swivel.

remember when tying braid straight to terminal tackle (swivels ect.) make sure you use a locked or "full" blood knot or similar which cant slip.

anyway everyone has their own point of view, the above is what I reckon best suites someone new to braided lines. keep it simple!

the only qualification I would make to my above statement (after further reading the thread)is that if using very heavy leader ie: 50lb braid to 120-150lb leader, you might struggle with an Albright. The FG would be more suitable as it binds into the leader (its not actually a knot). I still think you want to avoid advanced knots at this stage- without knowing what you're chasing its hard to comment but I would suggest going to 80-100lb leader if possible and sticking with an Albright knot to start out with.

pr knot is very simple to tie with a bobbin and can be used on any size braid or leader, heavy or light !
