The biggest "advantage" of Pushing over long line trolling is "control" .... you have less line out, so your turns or S curves or following a winding contour line are more likely to keep your lure in the correct path. With Long Line Trolling, your lure is much farther behind you ... so your turns have to be much wider, and your lures won't track as close to your path, but will instead simply follow straight behind you (more or less, especially on short S curves).
I rig mine with 1/2oz to 1.5oz weights (barrel sinkers) on the main line ... then a bead & a duo-lock snap. I have several sections of pool noodle with jig heads on 2ft leader lines, so I can change out quickly whenever I break off on a snag. I'm generally going at 0.8 - 1mph and use a spread of 3 - 4 rods when fishing solo. But, I'm still a novice at Pushing ... and just recently acquired two more long rods (which have line counter reels) to add to my 3 other long rods (which have baitcast reels), a double seat setup & a long handled net. I've yet to have the chance to use my newly acquired equipment, but have used these same items in the boats of a couple of my friends, so I won't be totally ignorant when the time comes to do it out of my own boat.
