You can't, or at least aren't supposed to, leave any crossbow cocked and locked for more than several hours at a time. With steel prod crossbows like Wyvern's and mine, you have to relax the limbs every couple of hours or risk the limbs taking a set and losing power. So you won't find any knowledgeable crossbow hunters sitting with a cocked and loaded crossbow for a solid 12 hours.

I don't deny that there is a definite difference between having the crossbow pre-drawn and having to draw in the immediate presence of game.I define immediate presence as the animal is offering the shot and you draw, aim and shoot, right then. Even drawing and holding as little as 90 seconds with a compound while waiting for the perfect shot does not qualify as immediate presence, in my book though. Anyway, it's advantage to the crossbow there, and nobody will deny it.

But you also have to consider thatcrossbows have the disadvantage of being a helluva lot noisier, even louder than the loudest compound. The noise is more likely to make a deer jump the string than with a conventional bow. Advantage and disadvantage. It works out as a wash.

I wish we lived closer together so we could go out and fling some arrows, and I'd let you have some trigger time on my midieval crossbow if you wanted. Let you see if it's really as much of a game killing machine as you imagine.(Don't forget, you represent a company that manufactures a crossbow. A very high ticket crossbow at that. [:-])
