You'll definitely not regret the Kadees. The uncoupler - maybe. I would get one or two of the above track magnets first and try those out before committing (you may have to raise it slightly). Get both a delayed and a non-delayed magnet that way you see the difference. If you go with the delayed, you obviously will need less uncouplers. The swizzle stick seems to have become SOP. I prefer the swizzle stick. There are also magnetic wand uncouplers such as the one made by Rix.
