Heading out next Sunday from Pa 501 for 4 weeks. Just curious if a 40 bag with liner will work or do I need the 20? Don't really see any cold cold temps in the long range, but we all know that can change.

What are the bags and what specific liner? Do you sleep warm or cold? Would you rather carry a warmer bag or sleep with all your insulating layers on?

20 is a WM Alpinlite and the 40 is a Kelty and no I really don't want to sleep all layered up. My liner is a silk liner that says it will give you up to 9 more, but I doubt that.
Definitely take the 20 degree bag. I started my thru on April 9 with a 20 degree bag and spent several nights when I was cold.

what is Pa 501? if this is in PA, then I would definitely say 20* bag.
one year my grandparents were snowed in from April 12 to tax day. not all that unusual...

After being uncomfortably cold 1 night, I swore I would never be cold again on a hiking trip. I had 3 layers of thermals on and I was still cold.
When all else fails, I want to KNOW that I'll be warm enough inside my sleeping bag. I bought a zero degree bag. 15 degrees out? I'm warm in my bag with only my base layer on. :)

Do keep in mind you are packing for the lowest possible temp. not average temp.
A related question. Where do you go to get info about lowest temp? Instead of average temp.
Thanks!!

For a 4-week trip in PA in April and early May, I'd bring the 20. Yeah, I'd probably be using it as a quilt most nights, but then there will be that one cold snap when I'll really appreciate it. I had a Kelty 40F bag and it was really a 50F bag if I was lucky. Nice bag, but not very warm.
I have a 20degree Z pack bag, @ 20 degrees I want my base layer on.
20 is a WM Alpinlite and the 40 is a Kelty and no I really don't want to sleep all layered up. My liner is a silk liner that says it will give you up to 9 more, but I doubt that.
Take the Alpinlite. You really don't have to ask. Take the liner if you want to keep the Alpinlite clean or need to use it as a sheet on top of the Alpinlite if you encounter warm temperatures.
You didn't say which way you are hiking. North or south?

I've hiked the AT through PA and personally I'd take the 20-degree gear. The coldest night I ever spent on the AT was in August, because I thought "summer, it's gonna be warm, if not hot." FAIL.
Also, at the end of a long, strenuous day, my body metabolism begins to shut down and stops generating internal warmth. I actually shiver if I'm not careful, even often on summer evenings on the trail. Not to mention, but cold fog with a breeze? CHILLY!
It's easier to cool off than heat up in cold weather.

The Alpinlite all day long. I have that, a Kelty 20 degree bag and a US Army issued 40-50 deg bag, and believe it or not, the WM is still my lightest bag.
I use a 45 degree bag between May and September.
I used a 40 degree ag for 2 years of prepping for a thru hike. The week before I left for Springer I bought a 10 degree Western Mountaineering down bag. Best thing I ever did. You can switch the bag out when you hit the mid section of the trail during warmer weather.
