How about Canson rag photographique 210gsm, nice feel, no OBA, not very textured though... (I like the 310 version)
Moab has the Entrada Rag Natural 190gsm, double sided, available in a 13-inch roll (Never tried this stuff myself but thought I would mention it because it's almost impossible to find 13-inch rolls)
If the texture is important, you could try the Hahnemuhle William Turner, which is available as a 190gsm version.
