I purchased two of Tim's quilts about a year ago. Both are 40 degree wides, half taper, overstuffed. When they arrived I could see that the down had shifted, especially out of the central main torso area, which had limited down left in it. I contacted Tim about this and he explained that I just needed to shake it out a bit.
I haven't been able to use the quilts much (it's been a tough year). Overall I haven't found that the Karo baffles do a great job of keeping the down in place. You can move it around, but you have a lot of variables in order to get an even distribution, as each baffle can move down to or move down in from lots of other baffles. This is OK to do at home, but doing it in a tent or when you are in the quilt isn't easy.
I would like to see the baffles made smaller and the gaps made smaller. I also am not sure if being able to move the down from top to bottom is all that useful and just makes getting even distribution more difficult.
I will be using this quilt more for summer use (not for temps down to 30F), as it opens out to a full blanket. I have now got another quilt for going down to 30F and below with additional clothing.
Tim's quilts are very well made and excellent value.
