Ten years sounds about right. Just be patient.
Seriously, I agree with Roadwarior, in that some of the more volatile aromatics tend to dissipate with time. Some of my own tobacco varieties, after resting for a few weeks out of the kiln, possess delicious flavors and aromas that vanish within a year. Others are harsh at that point, and really need a year or more to develop.
The "vintage" industrial cigars (properly stored) in the 10 to 25 year-old range are usually interesting, but seem to have lost their distinctive character.
All this notwithstanding, I believe that different varietals benefit from different aging. The aged leaf that Don sells is ready to be smoked after you roll the cigar--provided you roll it in the correct case. Setting them aside for a week or two usually improves their appearance, but seems to my jaded senses to have little impact on the flavor and aroma.
Rolling home-grown leaf requires experimentation to determine an optimal aging. Little Dutch and PA Red require very little time after kilning. Jalapa needs at least a year to tame down.
In terms of learning to roll cigars properly, "roll one; smoke one," is by far the most educational way to go. Roll them free-hand. Discover how you did (firmness, draw), before you roll the next one. Worry about cosmetics after 30 to 100 one-off cigars. After that, play with cosmetic accessories, such as a cigar mold. But, by all means, do the learning with good quality leaf.
