I am biased. I prefer CVA. They feel much better to my hand. I have wondered if the feel of the new one's Jon has been building are better. The Traditions I own are just not as satisfying to me.
Singletree is right about the main spring on the CVA. I've had to replace mine. I would add that the trigger/sear spring also failed over time.
I wish one of Jon's Traditions builds were nearby. I'd like to hold one. I am about to retire my 30 year old CVA from daily use. I need a new knock about, inexpensive, standard use percussion cap. I am gonna be very slow about it, but a new one is on my list.
