I've used the system and it has worked well. It is very easy to adjust the indicator for the proper depth. I also still use the dry and dropper method, as well as the slip knot method. Each has its own advantages and disadvantages.

The dry and dropper method is the most sensitive, but takes longer to adjust for depth (i.e. put on a new tippet between the dry and dropper). Still, this is my favorite.

The slip knot method is an old stand by and has worked for years. It takes a little longer to adjust for depth, but does well with adding split shot to get your flies deeper.

The New Zealand indicator is easy to adjust, but getting the right amount of wool takes some time to experiment. Once you get it right, it works good.
