Time helps these a lot. As izonfire said, "They smooth out considerably, losing their rough edges". Indeed. In place of the rough edges, you get added complexity. In other words, the usual trajectory and effects of cigar aging.
2+ years seems to be best, in my experience.
My standard maduro precautions apply to this stick:
1. Drybox 24-48 hours before use if you store at 68-70% RH like I do, may not be necessary for folks who store at lower RH%.
2. Do not smoke on rainy or humid days, dry days are best
3. Smoke them slowly for maximum flavors.
If aged and these recommendations are followed, retrohales with this stick are usually a treat. If not aged or these recommendations are not followed, retrohales can be harsh.
Hope this helps.
P.S. --- Try aging the regular, non-maduro Diesel Unlimiteds for 5+ years. I have. Holy crap, cigar nirvana, at least with the particular circa-2012 batch I smoked in 2017. Who knows if today's production are sufficiently similar to the 2012 ones though. Might be worth a shot as a "time capsule" gamble, get a box cheap here and then stash 'em till 2024....
