What a bunch of non-sense with the draw length. There are plenty of guys and gals with 25" or even less draw length. Myself included at 25"-25.5" dependent on clothing bulk. If someone sheds the money for custom bows made for his draw length, it is usually right.Not everyone is 6'-2" with 30" draw length.
Now, the advantage with wood is, that it comes in all spine weights, it just needs to be sorted. Carbons usually differ 15# and then you play with length and point weight. But plenty of times this will not yield the combo you really desire. A proper wood arrow is usually more quiet and flies just as good as carbon or aluminium.
With wood arrows,also always start out with full length, cut down yourself as needed depending on how it shoots.
