Ok, I've been watching all the diy UQ's, I have material, down, and even cut the noseeum.

My basic design is: 55"x42", 2" baffles, diff cut...

I have 1.1oz bags of down. According to Meteor's spreadsheet, I can go 5.5" inner and 6.25 outer on the baffle spacing, that get's me to 1.1oz/tube.

Then I started looking at everybody else's designs that had fewer baffles... since I'm stuck (again) in analysis paralysis I wanted some input from those that have done it:

Forget the down bag size, how wide should I go on the baffles?
