$389 for a SS Thumbhole is a good deal, you have a wonderful wife to get you a gift like that. I have an Omega, it likes 100g T7 loose with a 300g Hornady XTP or Nosler Partition with a Harvester Crush rib sabot. I use the XTPs for plinking and thePartitions for hunting (they about about $1 each, butthe XTPs are only .10 each). I bought a bunch of different bullets and sabot and found what loaded good and what shot good out of my Knight and my Omega, I believe that is the best thing to do for both learning and finding out the sweet spot for your bullet/load combo. I clean after every shot, even in the field, with 2 swabs of bore butter. You will not have a loading problem if you do that, you also won't have a 2nd shot, but honestly I have never needed one, and you won't either with that rifle. Get a good 3x9 scope. REad www.hpmuzzleloading.com or chuckhawks.com for some good scope info. I have a Bushnell Firefly elite 3200 3x9x50.

If you don't have a friend into muzzies, buy this book:

http://www.amazon.com/Successful-Muzzleloader-Hunting-Peter-Schoonmaker/dp/0873497465/sr=8-1/qid=1167186072/ref=sr_1_1/105-2464496-0735609?ie=UTF8&s=books

and read it. You will learn a lot. Shoot it a lot in off season to get familiar with it and most of all have fun with it. I think that muzzies are a lot like modern compound bow hunting---real real fun and challenging.
Best wishes for learning your new rifle.
