I bought Leader Grips, much cheaper than Red Snappers, then bought 3/8" water line tubing, at someones suggestion, now have same system for about half or less the price of Red Snappers. I, too, have zippers on my leaders but still have to pin or baste backing to 2nd leader. What helps most in putting on the leader grips by myself is having short sections of the leader grip to hold the backing in place while I fit the long sections.
