Query for the wise:

I really enjoy my new hammock, the UL BMBH by JRB. You know it well enough by now. I didn't enjoy the realization that my current batch of tarps is lacking an appropriately sized tarp for the UL BMBH. I'm looking for some information that I thought someone might already have come across. Specifically, what on-the-market tarp is the lightest that works well with the UL BMBH? - & - In your opinion what would be the ideal tarp dimensions for the hammock (with as little necessary tie-outs as possible)? Thanks for any info.
