You may ask yourself, why would anyone want a stinky highrise feed?? They are ugly, they make your hopper stick up too high, come-on!!! But back in the day hopper technology was nothing as to what it is today. To put it bluntly, hoppers were slow... The 12 volt revvy was the best thing around. And it could easily be out ran with a nicely set-up cocker. And eyes and antichop bolts were not invented in the paintball world yet. But by adding a highrise feed, you has a couple of more shots to allow your hopper more time to fill that feed back up. Three shots sitting in the feed as compared say 5? And it did it's job to a point..
