What are you using the rod for? Bass if so what lures are you going to be using, the reason I ask is that if you're using a Jig you're going to want to up your line weight to something like 17#. You mentioned that you're new to baitcasting, a couple of tricks I used when I was first learning to cast to help manage backlashes, is set the tensioner knob so the lure just pulls out the line, then make a long cast and pull off another 20-30' of line from the reel, place a piece of electrical tape across the spool and reel the line back in. Now the backlash will only go as deep as the tape.
I have been using the Alberto knot and really like it, it's easy to tie and one of the strongest knots when going from braid to Fluoro. I mostly have been using that knot on a spinning rod, for baitcasters I usually just like to run straight braid or straight Fluoro.
