Nice rig. Those Conquests absolutely rock for the money. I've got the same glass on a Winchester 70 in .30-06.
And the Badger makes a pretty good hunting blade. The whiskey is for deer camp at the end of the day.
The new versions should fit the bill quite nicely as well. However, you're right in that the TAC versions are going to be bulkier. If it's a thinner, smaller blade you prefer (and I do), then the BR Gameskeeper is going to satisfy you a little better. One of the things that bother me about a lot of the BR hunting knives is the lack of a guard. The new Badgers do effectively have a guard in the form of a handle curve and talon hole. The Gameskeeper too has a guard, though still a bit smaller than I like. When hands/gloves get bloody, the last thing you want is your hand slipping down on a sharp blade.
I've been moving away from bigger knives (like the CS Master Hunter) to smaller and smaller fixed blades for dressing deer (though I have begun carrying and using a Gerber bone saw for the pelvic bone). In recent years, I went from the Master Hunter to a Buck Vangard in ATS-34, a smaller knife. Now, I tend to either carry a Safari Skinner or a Denning custom hunter, even smaller knives.
Still, you NEED to pick up a Badger. Once they leave the shop and the company store as offerings, you'll never see them at these prices again.
