Any suggetsions for a thick paper for Falcon II?

[SwiSh]

I'm looking for a thick paper to use on my Mutoh Falcon II Outdoor. I've used InteliCoat Poster Paper (10 mil), but was unhappy at how the black inks layed down. Still looking for the same thickness, maybe thicker. I was wondering what other people were using, or if anyone might have any suggestions. Thanks!

How thick? Grimco sells Sihl TriSolv, good and cheap.

I used Tri-Solv, but I couldn't find it thick enough. That's why I switched to a 10 mil. Any help would be appreciated, Thanks!!
