Andrew,
Welcome. I got the double as a starting point and loved it. I bought two more. I got the slap straps pro and they don't stretch over time. They stretch immediately and they do it every time you put up the hammock. I set it head height - straight across between the trees. After I put my weight on it (arm pits), it stretches down and down. Very inconveinent.
I had some poly straps (like from Home Depot, used to strap stuff down), but the cam got in the way. Did it once car camping and couldn't get the knots out.
I got some poly straps like this:

but I need to get more as I have some more hammocks to string up.
The biggest difference was when I switched out the Slap Straps with these:

I heard all the 'hype' on here about them, so I got one pair. Amazing difference. Don't waste your money on the slap straps. Get a pair of whoopies and about 8' of poly straps for each tree. Get an extra whoopie for the ridgeline like this:

These changes will definitely change the basic ENO double to a great hammock. Read through this forum under the ENO and you'll get a better idea.
