As usual, for me, I am reviving an old thread rather than starting a new one.
I've been using my stacker for Raccoon hair recently, and realized a problem that's always bugged me, has a pretty simple fix.
Problem: The fine tips of the hair is a pain in the neck to get it all into the stacker. Even with the flared end, I always end up with some of the hair twisting up, flipping out or fouling the process.

Instead, I started putting the clipped ends (neat and even) into the other end before inserting it into the outer tube.

It's then much easier to slide the whole batch of hairs into the tube.

After stacking, lift the inner tube 1/4 inch or so, hold it there and lightly tap a couple of times.

This addresses the other problem I had, pulling the hairs out after stacking. Tapping them down before separating the tubes, leaves the ends out far enough to grasp.

This might not be a problem to many ... but they make it easier for me to stack the fine, light Raccoon hairs.
