The flavor profile you seem to be after is probably my favorite as well! You should definitely try the Diesel. For the price, it's hard to go wrong. If they're too strong when you get them, let them age--the mellow out a bit and become more flavorful (or rather, the flavors blend together better).
Beyond that, you're definitely missing out on some other great sticks in that general PAM/LP#9 profile!!!! BTW, I assume you've tried the other Liga Privadas, including the Undercrown, if not, that's you're next stop!
What else you're missing:
La Riqueza (seriously, get on this asap! They get better and sweeter with age)
El Triunfador Lancero Especial (the Broadleaf lancero ... awesome stick, gets much better even with some age)
Cabaiguan Maduro (the non-lancero sizes of the above, the 46 is my fave)
Tatuaje 7th Reserva (good cigars, must try)
La Casita Criolla (incredibly unique cigars, also a must try. The corona size is quite a bit spicier, but still just over medium)
La Aroma de Cuba Mi Amor (a BOTL bombed me a few of these recently, and they're REALLY good smokes!)
Murcielago (just a great spicy-sweet cigar)
DPJ Series JJ Maduro (becoming hard to find, great Broadleaf Maduro cigars)
My Father Le Bijou 1922 Petite Robusto and Corona Gorda (these two sizes of this blend are great, but the cg size was an LE and very strong)
Illusione Maduro (the ~hl is my favorite vitola, but all the ones Iv'e had are good)
Oliva V Maduro (these are quite a bit stronger, but awesome)
Oliva O Maduro (like the V, but less strength. The perfecto vitola is awesome)
La Herencia Cubana Oscuro Fuerte (another cheapie from CI blended by AJ, also noticeably stronger but with a lot of sweetness)
Perdomo Lot 23 Maduro (another cheapie, surprisingly good, but medium or even less in body/strength)
EPC Maduro (a good standard yummy Nica maduro)
EPC Dark Rituals (just has my first one on Tuesday ... great cigar)
EPC Elencos (I've only had one of these, but I'm planning to smoke a LOT more!)
CAO MX2 (spicy and sweet without a lot of strength)
CAO La Traviata Maduro (more complex than the price would suggest, very nice)
Venturing outside of Nicaraguans and Blends:
AF Anejo (the first infused cigar ever, delicious, sweet, very unique, very awesome)
AF WOAM (classic, better than the other Hemmingway Maduros imvho)
LFD Cabinet Maduro (more like medium, but delicious!)
LFD Ligero Oscuro (not as strong as it sounds, barely full-bodied really. Better than the natural wrappers for me)
LFD Double Ligero Maduro/Oscuro (strong, yes, but really tasty, especially if you like chocolate-covered fruit!)
