I must say I like the new ProHunter stock and forend. I don't know personally how it handles the recoil, but I like the new forends, they provide a better grip when wearing gloves. Are the ProHunters overpriced? Sure. $800 or $900 for a muzzleloader is ridiculous, but they are selling like crazy right now. I've read T/C is offering a swing hammer upgrade for regular Encoresfor $70 or so but it must be sent in to T/C. I don't know about the swing hammer yet. You can save some money and just buy a hammer spur for like $10-$20 for regular Encores.
My buddy just bought a S/S Laminate Omega, they are sweet looking guns. Only knock on the Omega is you can't adjust the triggers, but I have read they aren't too bad to begin with. If you think you want to use another barrel, get a regular Encore or a ProHunter. If you have plenty of other rifles, stick with the Omega.
You could just buy the ProHunter and then you wouldn't have all the stress about what to do!
