I used a HH hex which has a 10 ft ridgeline for a while and it worked very well for my BB. I now have a AHE Toxaway tarp with a 12 ft ridge. I think thats about as big as you want to go. I know I have to get trees about 13 feet apart to get this hung tight. I also set it up with an adjustable ridgeline with prussics so I can slide the ridge around to center the tarp above the hammock. The hex style with 4 tie outs is the way to go for good general coverage.
