Weight
Wood varies a lot in weight from tree to tree, so no shaft is the exact same in weight.
In fact, each shaft is unique in several ways, making your shaft different from all others.
These attack shafts average around 1 lb 9 ounces, (2x the Poisonwood attack shafts).
While some lax players are drawn to lighter titanium or scandium alloy shafts, they are much more expensive and considerably weaker for a difference in only a few ounces! The wood's extra ounces of partially rotational weight are utterly unnoticeable even to the smallest 85 lb member of the lacrosse team and will not pose a problem on the field.
However, that extra weight will allow you to create SIGNIFICANTLY harder checks to your opponents, making you the most feared member of your team.
