I actually had the means and opportunity to see one of my favorites not long ago on a trip to L.A. - Katie St.Ives. I was browsing P411 out of boredom and came across her profile (
https://www.preferred411.com/P219088). I had just had a favorable trip to Vegas and had the cash and figured 'why not, dammit!'. $600 is three times what I usually pay, but it was a once in a lifetime thing. It was one of the better experiences I've had - she's a non-jaded, enthusiastic, perky pixie that wouldn't stop.
Katie St.Ives
As for my dream-cum-true, I'd say Lily Ivy
or Viola Bailey.
