Laminate MDF: Which circular saw blade?

I got one shot at this, to make a nice clean cut on laminated MDF, about 2" thick. I have a circular saw, was hoping to use one of these two blades. Thanks!

I had used the blade that had been used on many projects prior here when I cut my counters some 15 years ago. I recall cutting from the back side.
Just go slow, and use a guide, maybe clean any residue from the sides of the blade first.

You want the "a-face" to be entry point of the cut so that any chipping/blow out occurs on the "b-face". Circular saws spin such that the bottom is cut first which pulls the saw to the material rather than push it away, increasing stability. So, yes, you're correct. :)
