I base my likes and dislikes on accuracy , I have never had a problem getting a knite to shoot excelent groups , a friends t-bolt did have problems jamming the bolt with primer fragments , but would shoot great groups , other than that particular gun , all the knites I have shot preformed flawlessly . TC on the other hand , I own an omega , several friends own contenders , we have all had difficulty getting good groups , the guns function well , but in MY EXPERIANCE , knites have proven easyer to get good groups with , and they load easyer allso .
The disc extreme mentioned above has proven to be an excelent gun for me
