I've never used the multi tip system so can't comment on its merits. I'm the old fashioned type who still packs 4 rods in the boat, each with a different line. Two floating... one to hang out on the rod holder with a chronomid with the drag set fairly tight so the fish sets its own hook while you use one of the others...one floating for the Tom Thumbs or the weighted micro leach on a long leader, one sink tip to get those damsel nymphs down where they belong, and the full sink to get the shrimp down in the shoal where they belong. With this method you find yourself so busy that it cuts down the beer drinking and, as a result, save gobs of money.
I would suggest that before you buy into the multi tip system you get good at using a floating weight forward line. This is relatively easy to use and good for beginners (and old guys too).
I see the multi tip system more for river fly fishing than lake as you only have to pack one rod.
Just my thoughts.
