So, you are going to try it out minimally equipped and unknowledgeable (aka not even trying) and that will be the basis for determining whether hammocking is right for you?
Based on what you say you are bringing; hammock, bag, tarp, (I'm assuming a sleeping bag) I can guarantee you that it is not for you and recommend that you don't waste a night's sleep if that is truly your basis for comparison. I don't know what elevation/climate you will be in, but I have been miserable in 50*F temps and I was trying.
Not trying to call you out but I've seen so much "hammocks aren't for cold temps", "hammocks can't handle weather", etc on this forum and its because people are cutting corners with the apparent idea that hammocks are some sort of magical solution. They're not, they are another choice depending on your preferences.
Hammocking is not and should not be considered a replacement for floorless shelters/tarps weight-wise. As I previously mentioned, they can sometimes be heavier than a double-walled tent. They are meant for convenience and comfort not necessarily UL.
