If you cut the leaves completely off while they are wet (manicure wet), and then dry them, then you also have a good chance of the smell being lost. This is because much of the dank smell comes from the resin glands on the buds and leaves. If you remove many of those leaves, the buds will dry more quickly, and the smell will be lost. You need time for the chlorophyll in the cells to break down while drying to ensure that there is only odor from the resin glands coming off of the buds.
You are completely right that the "hay" smell is caused from chlorophyll being left within the leave tissue and cells. But this only occurs when there is excess leaves left on the buds and they are not dried completely. Because chlorophyll is locked into the plant and is not dried and broken down into a simple sugar molecule, the chlorophyll is locked up in the state that it was when the bud is taken off of the branch for curing.
For best results, dry with "sugar" leaves on the buds until the stem is dry enough to break, then it is time to manicure and put them into the turkey bags/jars for cure. Hope this helps and doesn't start an argument thread (this conversation always does)! -Cheif
