I think the maduro's are worth it,for the naturals,its a bit pricey imo.The naturals are avg.
All the ones I have had,nat. and mad,were beautifully constructed and both boxes were consistent in that they had no plugs,tight,or loose gars.
The maduros need a few months minimum rest to bring out that wonderful sweet perdermo maduro flavor.
Bobalouie doesnt like the perdermo maduros but I love em.

Also,try and stick with ring gauges above 48....maybe 44 46 areas will work but I found the smaller gauges to be tighter in draw and some had plugs.

Hope this helps.
