i am about to make my second UQ,this one will be goose down filled,but what i was hoping to find out is whether horizontal or vertical baffles are best,if in fact there any differences at all,all suggestions and or comments would help.

Baffles that go parallel with the ridge line is the way most of them go. The baffles can follow the length better than the width. You could probably go perpendicular to the ridge line, but the fabric would have to bunch up more on the inside part of your UQ.
good luck on the project
Another vote for parallel to the ridgeline. There's a lot less curvature involved in that direction so the down won't be a apt to migrate to the center of the quilt. If the baffles run cross-wise, they will form a "U" shape, making it harder to keep the down from shifting.

some good points.
On my DIY I will be going parallel. I feel that this will fit my needs and my skills!

I'm not seeing how down in a 50+" tube with the lengthwise gradient is more stable than down in a 35-45" inch tube with the more extreme crosswise gradient. Yes, the down could shift towards the middle, but does it?
Would more fill resist that shifting? Shifting would put more insulation, right where you want it.
My assumption was lengthwise was faster/cheaper to build. Why are there no quilts/sleeping bags using lengthwise baffles? Same down, same fabric, same users, but a different configuration?
I've had bags where the down shifted when side sleeping, but that was a fill problem, not a design problem.
Crosswise baffles on an UQ would make it tougher for the convection currents.

Hi Fish
The common wisdom is longitudinal, not lateral. Its possible to push the down around in the quilt like this, sewing is easier too. Also, with lateral baffles I'd want to use c-shaped baffles that I don't believe are necessary on a longitudinal construction.
Being able to move the down is a bonus. One night, I may be wearing a thicker hat or different combinations of top insulation, or I might have cold feet. The down can be moved around a bit to make it warmer at the ends or the middle.
'seams' theres more to this than meets the eye!
Jacks make there quilts with lateral baffles and I've yet to hear any bad things about their quilts.

The lengthwise is much easier and faster to build. Top quilts are the opposite - takes twice as long to make as there are more (usually) baffles and your working with smaller amounts of materials.
I recently had the down shift to the center in my UQ - it took a full month for it to happen - I kept wondering why my shoulders and legs were cold. My hammock stays up 24/7 as it's my "bed". I took the UQ and shook everything back into place. Took a whole 30 seconds to do. I'm warm again.
With the proper amounts of down in each baffle the shifting problem is minimal. If you overstuff too much, then you have problems as the down really does have mass and will gravitate to the lowest spot after awhile. This is true for both vertical and horizontal baffles.
So I built my UQ with horizontal baffles and the TQ with vertical baffles.
