Historically, I've fished a lot of straight braid. The past year or two, I've started using leaders more often than not.
You'll catch fish, even in clear water, on straight braid... but I must assume that, especially when using slow moving baits, a transparent leader will get you more bites. You rarely see guys in the Elites fishing straight braid unless it's their frogging rig... a few for flipping/punching.
My Logic:
Braid is arguably the easiest line to cast, has great longevity, and unparalleled strength. Braid is my mainline of choice 80% of the time.
Rocks cut through braid like a warm knife through butter, and braid (especially 30# and down), has the tendency to snap (heavy lures + backlash, quick hooksets)
Flouro can be hard to cast but is invisible, abrasion resistance, and has a little bit of stretch.
Fouro's strengths almost perfectly compliment braid's weaknesses! They are like pizza and beer - why wouldn't you put them together?!
Not only is the Albright not easy to learn and reliable, it will make you feel like a man after you do it right.
