Excalibur crossbows

[Chief Broom]

I like the idea of recurve simplicity and the Excalibur range seems to be the most respected and now it comes down to which one. Having arthritis creaping up on me and a bad back I wont be opting for a 400 fps model so am looking at the 330-350. Top of the range is the assassin with a built in crank and 360fps but expensive and will that crank be problematic years down the road.....hmm think i'll go for a matrix bulldog 330 or maybe a micro 350. Still a heavy draw weight but will probably manage and can have a removable crank as well if my back isnt having it and vertebrae deciding on a lateral leap..****.that hurts. Ive read that anything over 300fps is sufficient for any large game in the uk so either of these models should do. Anyone have long term experience of Excalibur crossbows?
