First Overnight Hang

[HillbillyHanger]

Next Friday night, I'm planning my first overnight in the hammock (Hennessy Explorer Deluxe Zip). I'd like to ask opinions about my strategy for bottom insulation for that first trip. I would expect around 55-60 F for an overnight low where I'll be sleeping.
I have a Big Anges 15 degree bag and I planned on taking my insulated air core pad (slightly inflated) and putting in the sleeve? Is this overkill for 55-60 F? I also have a Zlite sol that I used in the past under the Big Anges when camping in the 15-20F range. Should I put the Zlite perpendicular to the Big Agnes (under my shoulders)? I also have a surplus MSS sleep system. Would it be better to use the Goretex Bivy and patrol bag?
In a tent in this range, I would not even use a sleeping bag. I'd just use my Sea-to-Summit liner and sleep on top of the pad. I just don't have a clue what to expect. Long-term, I plan on pursuing the underquilt, but I do not want to be miserable until I can make that happen.
Thanks in Advance,
Mike

I think you should be fine with the pad for this trip, but it's very personal. If it's your first night, I'd stick around where it's easy to bail out.

Disclaimer: I'm a nearly-inhumanly warm sleeper. View this in that light.

If your top insulation (the bag liner) is good to the expected temperatures, the two pads placed into a "T" formation will do just fine for most folks at that temp. I wouldn't even worry about the second pad, if my top insulation was fairly incompressible (synthetic rather than down). But, to be safe, it's probably worth taking both.

I wouldn't worry about using the 15* bag; that's probably way overkill for those temperatures. The MSS might work just fine. If memory serves, the survival rating for the patrol bag is something like 40*, right? So, it should be comfy at 55* to 60*.

Is this a car camping trip? Or are you hiking into where you're going? If it's the former, bring everything and give it a go. Worse comes to worst, you'll be too warm or cold during the evening and have to walk the fifty feet to the car for something else. If it's hiking, go a little overkill; better to have it and not need it than the other way 'round until you know your gear inside and out.

FLRider's first rule of gear testing: do it where you have a backup that you know works. Either a safe place to bail to or gear that absolutely works for the expected conditions.

Hope it helps!
