Excalibur fan here. Have a 20+ yr old model that's never given me a problem. Just bought one of the new Micro Axe 340's to have a narrower more compact xbow and am impressed so far but it's much tougher to cock than my old long limbed Exocet. I will say that whatever make and model you decide on, get a crank cocking devise for it. If you're not able to draw a compound bow due to your surgery, cocking one of these high poundage crossbows with a rope type cocker will be hard. Most makers offer an add on crank and some have one built in to the system. Years ago I bought my father a Ten Point with a built in crank and he used it to take a few deer, the last one when he was 91 yrs old!
