RE: carve122 2006 d-ram or 121 2005 wood?
I'd get the more modern shape and its 1 more year of development.
As for weight: if you read board specs on Starboard's present and old catalogues, you will see that differences between D-RAM and Wood can be very limited and in some cases the difference on a given board model is well within manufacturing tolerances (meaning the lightest D-RAM samples can be lighter that the heaviest Wood ones). This to me means that weight is not an issue in your kind of choice when compared to others such as strenght and ease to repair; expecially talking about a freeride board.
In my opinion and from my limited experience (I own a D-RAM Evo and a Wood Sonic, and owned two D-RAM HS) probably the main difference on the water would be in that peculiar nice "damped stiffness" feel of wood boards; but again nothing too much important on a freeride board.
