Rip -- why taper the leader for streamers? My understand and experience with tapered leaders (which you've seen on here before) is that they're good for transmitting energy and "softening out" your cast and providing a more gentle landing. Aside from that, the heavier line at the butt and mid section doesn't sink as well as thinner line (like from a lever leader). I was just thinking that you'd select a level leader for these flies as well -- is presentation important in the surf?
I don't mean this tongue-in-cheek -- I'm genuinely interested in knowing. You appear to have been at this game for probably at least a decade longer than me so I wanted to pick your brain, and possibly avoid mistakes before making them
