I just came back from the dentist and sitting in the waiting room I was reading a copy of F&S Nov 2015 edition comparing break open MLs. The 4 "experts" tested the CVA Optima V2, Traditions Pursuit G4 Ultralite , T/C Impact and Knight Vision.
Overall test for fit, feel, reliability, function and ease of loading/priming and cleaning.
These four tested choose the CVA as #1 with the rest falling in the order listed above. Having read the reviews with the pros and cons I agree with the results stated about the CVA. Having no experience with the others I have no comment.
