There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars).

I have 3 EE bags, 20 and 40 degree Down, and the 50 deg Synthetic (Apex) Revelation, and would recommend - Why 3? I use a layering system to match the season/weather. 20deg +40deg = the loft of the 0 deg bag. with only a minimal weight penalty, but a bonus extra baffle :D - All are Reg/Wide and fit me well at 6ft, 220lbs - Reg/Wide fits/works as an under quilt for the WarBonnet RidgeRunner
The fill power of the down should not impact the target loft in any way. Fill power represents a weight to volume ratio. Temperature rating is related to volume of fill. Lower fill power just means the fill used to get to that needed volume weighs more than would a higher fill power down (and is lower quality, shorter life, etc).
Enjoy your RidgeRunner!
