I usually don't respond to these threads as they don't seem to go anywhere, but I think I can add something to this from experience and maybe help Wissler make a decision (nice buck in your profile pic btw !).
I've killed a few black bears with a handgun and a number of wolves with different firearms but none of either were charging. A wolf takes some killing for its size but of course they're really not that big and if it works well on a whitetail it should work well on a wolf.
I've only had one wolf follow me close that I know of and it just seemed curious, it got as close as 30' ghosting me. I was armed and didn't feel threatened in the least, in fact when it got tired of watching/following me I started following it just to watch it for longer. It was late spring, season was closed, or it would have been a dead wolf. I don't even consider wolves when I head out the door, but as previously stated, a schoolteacher was run down, killed, and partly consumed about 150 miles or so from here, just 3 years ago. But nobody seems to remember when it ever happened before, either.
The whole charging bear thing. About every year I take and sometimes help teach a bear safety class as part of what I do for a living, the class was also mentioned previously. Yup, buckshot is considered unreliable for bears, and personally I always thought buckshot was for coyotes and people that couldn't shoot lol. But for wolves, it has sometimes been used for the aerial shooting that has occurred and it is effective at close range.
My only experience with pepper spray is firing off the test ones that only have water in them. One reason I don't like it is you can't take it on planes of any kind as there is a danger of it discharging so that limits things but mostly I'm probably just old school in my attitude towards it.
And if it was me in your situation, I'd just carry my bow because I like to do that and don't forget it is a very effective weapon. And enjoy the wolf howls 'cause that's pretty neat stuff.
