Just a couple of other options.
One is to double the line over on itself to form a loop. Form the loop size you want. Place a couple of nail knots on it and cover them with Loon Knot
Sense.

The other is to put a braided mono loop on the end of your line. Once the loop is installed, you can tie a perfection loop on your butt section and blood knot your leader to the butt. You can also just tie the perfection knot on the end of your leader and connect it directly via loop to loop.

If you are fishing mainly for trout, attaching the butt with a nail knot is all you really need.
