F, according to Martin's website, the D-16 is long scale, the 000-16 is short (as is pretty normal). What you hear in tone wood is what YOU hear, don't listen to what anyone says you should hear. In fact, I can point you to two very scholarly studies that conclude that people really can't tell what they are hearing in tone woods. It would be worth your time to play two more or less identically built guitars while blind folded - say a D-18 and a D-28 since you like dreads. Have a lovely assistant help you - do an ABX comparison. It can be rather humbling.... I'll also say once more time and I'll forever shut up, why anyone would buy a guitar without playing it based on the advice of an online forum of people who you have never met is beyond me. Make the investment in gas and time to play everything you can, pick the guitar that sounds best to YOU and buy the darn thing. Come back here and wax about your NGD.
