This should work for you - see below (Just practice a couple of times to perfect your nail knot 1st) and then you will be set for loop to loop connection with pre tied leaders. Another option is to use a braided loop connector at the end of your line if the line doesn't come with a loop already - also see below.
If your reel comes with a drag adjustment, it NORMALLY is located on the opposite side from the handle and is a little knob that will increase or decrease the tension of the line as it comes off the reel (if the line is wound properly on the reel for right or left hand retrieve what ever you have set it up for).
