Well fellas, I too was unable to chose between the Excalibur models....everyone of them seems to be the correct choice. After much debate, I purchased the Exocet 200......and what did I base my choice on was the 200 lbs draw weight was the max poundage allowed in my state of Pa. I figured , well , if I'm buying a xbow I'd go for the gusto of what I'm allowed to use and take advantage of that poundage which is legal here. That was my determining factor......even though I would have been just as happy with the Vixen or the Phoenix.
I do have an iffy lower back at times.....but that has never stopped me from cocking the Exocet.....I can shoot for hours , no problem......thats using the rope cocker of course.
And when deer hunting, when it's time to quit .....I can unload the xbow using the rope cocker......or by hand gently lowering the string down......a nice feature when it's to dark to see the rope cocker!!!!!!!
I feel I made the right choice.....right from the beggining.
