I have owned two encores and a Pro-hunter. I have also owned atleast four Triumphs. The Endeavor copied the Breech plug from the Triumph. Now the Bone collector is copying the Pro-Hunter/Endeavor on the flex stock. The Triumph is a better designed Muzzleloader then the Encore. As you stated if you want to switch barrels the Endeavor is a much better choice. If you want strictly a Muzzleloader the Triumph wins easily. Not to many people complain about the triumph. Almost everybody complains about the Encore. You just need to tweek it some to make it better. It's really no big deal.

BTW- I forgot to mention the Encore is my all time favorite factory Muzzleloader. Absolutely no doubt about it. I have said this many times and still feel the same to date.
