Just wondering, which hennessy did you try?
A safari should be about as roomy as it's gonna get. If you've not tried one see if you can. I hate answering with "buy more hammocks", so I don't know if trying all these different models is an option. If it were to fit you comfortably then add a Zipper mod (or not) and yer good to go. I have a safari and it's ridiculously large nothing touches me anywhere. course I'm only 6' and 250.
