Another plus for the sub-1 lite, no bow press needed to change cable and strings .I have the sub-1 lite and couldn't be happier. It's very accurate, quiet for a crossbow, easy to rope cock, and you can uncock safely without firing an arrow.
335 fps is plenty speed to zip right through whitetails and hogs which are the animals I hunt. I'm sure you would be happy with either the sub-1 lite or the Excalibur. Two good choices!
