i have the barnett rhino system 4 for 3yrs. now and have never had a problem. still even has the original string(which i will need to finally replace before next yrs. season). it has even fallen 20ft. to the ground once and nothing ever broke on it (just had to re-sight in the scope). eventually i would like to get a new one thats lighter and smaller when i have the $. as to what make and model it will be i'm not sure. i'll just have to test them out for myself.
