I passed on both the Drop and the Drop Dead because the flavor production I got from them left me wanting for more (using only the top row of air holes with the Drop). I do own the Dead Rabbit with the Priest cap (Challenge cap), though, and I also own the Vindicator 21700 kit that comes with the 2-post Kennedy 25 and the Stub Dogg (low-profile ultem drip tip) instead of the classical/old full height metal drip tip. In fact I own 9 (nine) Kennedy RDAs (a 2-post 24 and 8 × 2-post 25). The Kennedy isn't just "great for those who like really low ohm hot builds, or really big guys with really big lungs". That sort of stereotypical remark only comes from low wattge vapers who either can't or won't understand the simple fact that, without any vapor production, there can be no flavor production.
The Kennedy, while it certainly is capable to produce fairly big clouds, is especially great for those who, like me, get seasick if doing 7 second pulls and/or those who, like me, enjoy flavor by biting a good mouthful off of their cake instead of by snatching leftover crumbs with their fingertip. The Kennedy provides a reasonable (and perfect, at least for me) amount of restrictiveness if you do 2-3 second pulls and, during that 2-3 second period, you suck just hard enough to fill your (normal capacity) lungs just to the point where you don't yet feel inside your chest the high pressure effect you'd get from an actual deep inhale. With normal sized (7-8mm length, 2.5mm ID) Ni80 coils at ~120 watts, this will typically result in a moderately cool, not warm, vape experience that lends itself particularly well for the majority of light fruity flavors (i.e., that doesn't lend itself well for juices that only come to life after you add noticeably more warmth by designing your coil build specifically for that). So the re-occurring old "hot vape" myth is just classical user error 101. A complete and utter lack of understanding the normal basics of advanced coil building (e.g., fused claptons, staggered fused claptons, aliens) is obviously the culprit.
