I stopped by a store last weekend and looked at several muzzleloaders. By far, the various CVA models had the best triggers. I tried several models (Wolf, Accura, etc) next to TC Impact and i was surprised at how light and crisp were the CVA triggers. The TC Impact had much more weight on it and a bit of creep.
They did not have the Traditions Vortek, but i hear that one also has a good trigger.
If i could only get my hands on a CVA Apex...
