I have the yates aiders you're looking at, and I think they're pretty good.
You just need one fifi hook, girth hitched to your harness (I have mine on my belay loop)...to be hooked into bolts, biners, your daisy, etc. No need for other hooks if you're doing the pioneer route, 'cause the aid pitch is a bolt ladder.
If you want to do some aiding sometime let me know.
