I've shot some of the "PLUS" 400 in 135 in PMK
It's really thin base. I didn't notice scratches and I was spooling it myself from a 100ft roll.
It's not bad for the moolah.
Here's a shot in contrasty (hate that word) light.
It's a bit grainy and the s*an doesn't help.
I haven't really formed a solid opinion on this stuff yet.
