RE: knight disc or tc omega?
I agree with Triple Se7en, you need to get your hands on those models and shoulder them. The other day I got to handle a CVA Optima at Wal Mart and I must tell you, I did not like the way it shouldered. The T/C Black Diamond on the other hand fit me real nice. As for ease of cleaning, I have no experience on that. I still use sidelocks and as we all know they are a bear to clean sometimes. Although since I switched the one rifle over to only Triple Se7en powder I can not believe how fast I can clean it. It cleans up so fast I am always afraid I did something wrong, and still run patches through it to double check it. Good luck on what ever you pick!
