Maybe you could build a simple line chart with all the characteristics we are concerned with. Some things would be subjective while others measurable. Subjective items simply rate from 1 to 5 and measurable items such as Sg just list.
example, best being 5 worst being 1
Elm wood
SG 70, elasticity 4, tension strength 3, compression strength 3, bendability with steam 4 or dry heat 3, proneness to chysal 4, historisis 4, workability 4, Etc, etc,
