Matt,
When one of mine dies, that is going to be my next Dolphin purchase.. I'm jealous!!
As far as taking it in and out of your pool goes, when you take it out, I suggest you not wrap the cable up on a caddie..
My theory is that coiling the cable on the caddie and letting it sit for a few days causes the cable to become less flexible and increases the likelihood the cable will tangle.
I lay my cable on the deck with a couple of very large loops..
I think you will love it, no matter what your family names it.
