Yeah, upside down was killing my neck (and sinuses) so I started doing upright, and low and behold - the clumps held up! I guess for my hair setting the clumps where the live work better than setting them and then flipping up.

I don't do a single bit of it upside down (except on very rare occasions I'll apply stylets that way), and iget great results. I do clip the roots for volume, tho.
