For what it's worth I had this issue last year with some highly figured
walnut crotch.  Just maybe these thick blades are not better than the thin
ones on the original Stanley model?  I know it's heresy to think that thin
blades might be  better.
 If you have an old hand saw which isn't pitted (and not otherwise
valuable), cut a new blade for your scraper plane out of it.  Try that and
see if you find the same results I did.
 The LN Co has a video where Deneb fettles one (I can't recall on what
webpage it's linked from, but Google it).  I tried the method shown but it
wasn't good for the wood I was scraping (I bought one to try).  Didn't
someone here also mention wiping the wood with denatured alcohol
occasionally?  ...maybe that helped, not really sure.
One more thing about the thinblades-  Finding the right height, so that it
takes a cut without the thin blade making a clicking sound (it shouldn't
snap back)  at the end of each stroke is the tricky part.

How hard is your wood?  The softer it is, the more difficult it will be to
scrape.
