We should not be thinking of Longbows and bodkin arrows as these were developed much later.

Longbows are not composite, no matter how this statement is justified, they were made from a single piece of wood regardless of heartwood and sapwood. Longbows are self bows.

Bodkins were manufactured in two types, the needle point and short point. They were forged in a square shape that tapered to a point, long in the needle point and short in the other. The needle point was intended for use against mail, the narrow point would the pierce the mail link and as it entered, the four edges would cut/force open and allow the arrow to enter. The short bodkin worked in a similar principle to a punch tool. The sharp point was intended to make the initial piercinging of plate, the four edges would then cut and pop a hole into which the arrow could enter. Against plate, the needle point would have bent.

Even if bows used at this time were 'long', they can not and should not be compared with a weapon that rose to prominence during late mediaeval times.

Arrows of this period would also be nowhere near as developed as mediaeval arrows, even the Huns were still using bone arrow tips in many cases in 4th C AD
