I have run an eno knock-off for years, in fact, just came back from a backcountry fishing portage. I used to use a sleeping pad for under insulation, but now run an underquilt, bag/top quilt and a tarp. Packs small and light. I use amsteel blue for a ridge line and if it is buggy weather, I use some noseum to seal me in. It is not like a tent in that you will need to learn how to set it up long before you can set it and forget it. However, with the proper insulation, temperature is never an issue. I had a 30deg bag and a DIY Costco quilt for my underquilt this weekend and took it down to 25 deg up north last weekend without issue, just kept my base layer on.
The upsides for me are:
-where I go, there are tonnes of trees, so setup isn't hard (just pace out approx. 12-15 feet between two trees that will hold your weight, clear and under brush and hang).
-even though I sleep on my stomach at home, in the hammock, sleeping on an angle (with the hammock hung with the appropriate slack), I get a very flat lay which allows me to sleep on my side
-my back feels great in the morning
Downsides for me:
-its a solo shelter, so pairing up requires two systems
-unless you have/make some gear slings, your stuff is not generally in reach while in bed
-you have to physically get up and out of bed to make coffee, unlike a floorless
Hammocks aren't for everyone but since you have an ENO, test it out with some insulation(top and bottom) appropriate for the weather, chuck a tarp over it if it might rain and see if you can sleep in it before finding yourself hating life in the back country. Getting the right amount of slack during set up and using a ridge line are key for me.....
