Wise Muzzleloaders,

New to this site and to muzzleloading.Will be muzzleloading next year for the first time. I am an avid whitetail hunter looking for another excuse to spend more time in the stand.
Been trying to decide which muzzleloader to get by talking with friends, sporting goods stores and searching the web for reviews on various muzzleloaders for info.
I will spend some money if it is worth it. Not one to trade or sell guns much. Been shooting the same .308 and 870 for the past 24 years so want to make a good decision.
It will be a .50 cal. Was thinking Blued / Black but could go with stainless if it is worth it. I hear it is easier to clean. My other guns are blued but they use smokeless powders.
So far everyone is steering me towards the T/C Omega. I looked at the gun and it felt pretty good.
Have a couple of concerns though:
1) The trigger guard seems a little small for gloved fingers. I live in Minnesota where it gets cold during muzzleloader season. To get the hammer back quietly I need my finger on the trigger and the space is limited. Any opinions or solutions?
2) When I shoulder the Omega it feels pretty good but when I shouldered the CVA Optima it feels like my head was in a more upright natural sighting position. Seems like I hear of some manufacturing / conistancy probs with CVA though. I have also thought about the Traditions Pursuit. Any opinions?
3) I don't know about the factory sites on the Omega. I use a scoped rile most of the time. I have used open sites on a very old 30/30 and they were nothing like the Omega fiber optic sites. Are the Omega sites good open sites? In Minnesota we can't use scopes during muzzleloader season so good open site are important to me. I set my stands in positions where I feel comfortable I can make a clean shot. If certain open sites and practice will help more that out I'm all for it. Any suggestions?

Any input is appreciated!
