Crossbows in GURPS (Low-Tech)

For a recent TL4 game, I wanted an array of crossbows available for purchase, broken down by ST and performance, with commensurate weight, cost, etc.  Thrust damage has breakpoints at odd-numbered ST values, so I skipped the even numbers.

Min ST - Lifting ST required to simply wield the crossbow's mass in combat, independent of its draw strength.

Eff ST - Strength of the crossbow for range and damage purposes.

Draw ST - Lifting ST required to draw the crossbow. Use one of the drawing mechanisms from Low-Tech p.79 to increase your effective Lifting ST.

Crossbow - A simple crossbow, with a wooden prod of ash, hazel, or yew.

Composite Crossbow - Has a nomad-style prod of laminated horn and sinew construction. This example includes a Goat's Foot drawing aid (Low-Tech p.79), allowing a man with Lifting ST 11+ to draw the crossbow while in the saddle.

Steel Crossbow - A steel prod can be much stronger, permitting higher tension and striking power, but cannot be drawn as far. This requires additional mechanical advantage to cock the crossbow.
