Zen, you are lucky. I have tried using just a small amount of sportswash (half a capful) and it doesn't get the pee smell out at all and my dipes were coming out with stains, which they didn't when I used Tide. The worst part was that DS was getting a little rash and when I stopped using the sportswash he never got it anymore.
I think it really depends on the type of water and machine that you might have. I do agree that fibers do hold onto the extra detergent and I usually do an insane amount of rinses to get all the suds out. I think that because I have moderately hard water here, I need to use Tide just to get the diapers clean - I use about a 1/4 capful. I have a top loading machine.
