10 oz tarp, 10X12

[beezlebob]

Hope I'm in the right place. I just bought an 10X12 tarp to use at rondy's as tents are a mite expensive at the moment. I had a choice of 10 OZ, or 16 OZ tarps, and as I enjoy trekking thought the lighter weight might help.
  Did I make a decent choice? It's water resistant, coated with something, gromets every two feet. I hope I've done the right thing here. Comments please.

Light and waterproof are two things but I'd want to treat it for fire resistance slso. 10X12 should make a good diamond fly.

I hadn't thought of a diamond fly, great idea, thanks.
