 Rubberized shingles (?)

I know of a couple manufacturers of SBS modified asphalt shingles - Atlas is one and I think Malarkey(?) is the other. I read something not too long ago that more manufacturers are likely to move to polymer modified for their premium lines.
When mod bit first came out for low-slope membranes, most folks where calling them "rubber roofs". Now it looks like it's come up again for these premium shingles. Not a good idea since the "rubber" shingles could be interpreted as they're gettin' a synthetic slate roof.

I've done a few projects in the last few years where the owner upgraded to Malarkey Legacy shingles. They carry a 50 year warranty and they are kind of rubbery feeling.
I don't know if they'll really last 50 years, but I'm pretty sure those flashings won't.

Thanks Bill & Jim. Malarkey is just down the road in Portland, so I guess it could be those (not that I'm going to identify them in the report). Seeing the listing agent's sign in the kitchen was one of those "Huh?" moments. While I was yet to get on or up close to the roof, I had seen it. I was either having a senior moment or the sign was goofy.
Visually, I doubt I could reliably tell the difference between these and the norm. I will say that the granules seemed very well attached. It lacked that feel of loose grit you often get when walking on a newer roof.

Copied this from Malarkey's website. They are indeed claiming 50 years for their top of the line shingles.
Malarkey?s revolutionary Legacy? shingle technology begins with a durable base layer of fiberglass mat. Malarkey?s unique fiberglass mat is coated on both sides with the SBS modified rubber asphalt which provides tensile strength and increased flexibility, protecting your investment.
SBS MODIFIED ASPHALT
The rubberizing aspect of SBS increases flexibility and weatherability for your roof. The thermo cycling resilience of SBS modified asphalt provides greater granule adhesion for the shingle to create a better barrier from the elements. When granules stay on the shingles, you ............
