The Robusto size seems to be the strongest. When the box of these is fresh/young they are incredibly strong IMO, but in 6 months the strength really tapers; a cigar with a half life you could say. I am a big fan of everything coming out of Tabacalera Tropical. Depending on the price you are getting on the Mombachos I prefer the Nicarao line.

A quick google search turned up a box of 'em for sale. Anyone know where you can get singles? Sounds like they'd be nice to have sitting around for one of "those guys".Mombacho "Thermonuclear"
