Myself, I do a bunch of different things. For surfcasting and when using either spinning tackle (with Fireline) or conventional gear (with Berkley Big Game Braid), I palomar-knot the braid to a small barrel swivel, then clinch-knot a short, heavy fluoro leader to the other end of the swivel. The swivel, or course, stays outside of the tip guide when casting. When freshwater bass fishing using similar lines, I most often use back-to-back uni-knots in splicing on a leader, which creates a knot that can pass through the guides when I cast. That connection has only about 70 percent of unknotted line strength, but the pound-tests I'm using are high enough so I don't think that makes much difference.
