That Kelty tarp is PU coated and heavy stuff.
I'd go with OES if you have the time. Brian does an excellent job. My 3 season tarp is his MacCat Deluxe. If you want extra tie outs, he'll charge a few bucks for it, but you can get the configuration you want, including side panel tie outs if you want them. I suggest it because you wanted grommets, which he doesn't do - he sews on grosgrain/ribbon and adds D rings.
JRB does excellent work too. So do any of the hammock guys - Warbonnet sells tarps.
