I've got the Fireforce and the Stinger.
I pretty much agree with KLV has to say.

Though the weight isn't much of a factor if you've shot the Bowtech, Stryker much!!

I also have very good accuracy out of mine. I ruined two arrows...putting one into the back of the other until I started shooting only one per target dot. My target has four.
String life...much better than any crossbow I've owned in the past twenty years. Very light pressure on the track.

And last...my two must be off as far as the trigger. Mine have far and away better triggers than any crossbow I've shot...save for the Stryker, and they are very close. The Darton trigger does have a lighter pull from the factory.
Much more akin to a rifle than a crossbow, at least the ones I've shot.
