Excalibur 2014 Commercial - Crossbow Cross Examination
This may help you decide between different compound crossbows.
I personally have 2 Excalibur crossbows. I've had to change the strings each year and I can't shoot more than one arrow at a spot on my targets. I've split 3 arrows over the years.
Try an Excalibur before you decide. good luck
