I'd agree, Steven. Without something new, "yer pays yer money, an' yer takes yer choice!"
However, I'm afraid this is incorrect:
Consider:
Force =mass x acceleration;
Momentum = mass x velocity;and most important of all;
Kinetic energy = mass x velocity squared - which means a small increase in velocity, means a very large increase in kinetic energy to be transferred to target - think bullet: low mass,high velocity.
It is the shock from the transfer of energy we are concerned with, thus the need to withstand head-on shock ; hence missile weapons are made of heavy dense wood such as cornel ( the traditional wood for javelins) and spears from lighter woods such as ash - and it is the fact that a 'heavy' wood is specified for the menaulion that tips the balance in favour of 'throwing weapon' to my mind, as I indicated before...... :?

Quote:All of these argue for me in favour of something with longitudinal strength, suitable to withstand head-on shock, which is really unnecessary in a missile weapon......it is actually the reverse! Missile weapons move at velocities far higher than is capable of being generated by a thrust.
