If you got the standard 6' straps & 6' whoopies with your All-In-One then they should be sufficient for most trees. (upto about 2' in diameter) All you need are 'biners or dutch clips as mentioned above.
You can simply remove the heavy rope from the Eno's end channel and lark's head the fixed loop through it. Worked fine for me before I got my WBBB.
I have All-In-One whoopie slings from whoopieslings.com on all my hammocks now. IMHO, it's the only way to hang.
