While I have never tried either (so take this with a grain of salt), I wouldn't be afraid of the Eclipse line of blades - especially if your fitter is recommending them. That echoes the opinion of our best fitter within 100 miles.
I like the information about the blades on the Riedell/Eclipse web site. If their skates are as well made as the information, they should be winners. I'm getting Eclipses next time I get new boots.
Breaking in? - I've always just put as many hours on boots as I could, even attending rec skates to just stroke around and get used to them.
