On the Rampage, just take one and knock the shine off (maybe 2000 abralon) and look closely at the cover. The red is solid, and the gold is pearl.
Regarding the Monster Bruiser, I think the percentage of pearl additive was smaller on most of them that I saw, nevertheless, it was still there.
I never saw any of the Sidewinders that lacked the particles, but I don't doubt that it could have happened. I learned about that on this site. Who'da thunk it?
