If the sides start to split (typically lengthwise down the stick) it is usually from too much moisture. The tobacco swells and the thinner wrapper splits.

Smokes that are too dry tend to unravel.

I would retest all your hygros just to confirm - they can be anywhere from 1% off to as much as 15% off.

Hope this helps

btw-the "Short" Puck will fit in the lid of the humidification jar, leaving more room for a couple of sticks
