I'm getting an 8x10 Sinar P which I will be using outside and I'm wondering what people use for a dark cloth if anything. I have a blackjacket hybrid for my 4x5 Wista SP. I found it to be very hot (my only complaint). So more often than not I just use the built in hood of the Wista SP and shaded the GG with my hand when I used the loop. I've read the BTZS hood is hotter than the darkjacket in threads here. How about the Harrison Dark Cloth? I've also seen an ebony that goes over the entire camera and acts as a lens shade but it was a bit pricey.
