I usually get a commercial knotless tapered leader in the "stiff butt" class like ones made for bass, pike, and saltwater. I get a 12lb to 15lb tippet that is 9ft. After I have changed flies enough to add a few feet, I make a loop and just replace the tippet as needed.
I'll use the same leader for a year or 2 before changing. I keep a spool of 12 lb or 15lb basic cheap mono for tippet. It has been my experience that bass aren't leader shy. I will tie on 20lb when mixing it up in heavy cover.
My leader total length pretty much stays around 9 ft. With the stiffer butts and heavy tippet I have no problems even with wind resistant hair bugs.
When I trout fished I got all worked up over proper leader taper and high strength to diameter ratio expensive tippet material but don't worry too much for bass.
I also generally use a heavy snap (like in a snap swivel) to make changing flies very fast and makes for livelier fly presentation for subsurface patterns.
