That's the same spread as mine, and the generally agreed upon best nature for him. Obviously I'm a bit biased as he's my favourite FE character, but if you want to use him, you've got a great start right there.
With a Brave Axe+ and some nice inherentence skills, he is a force of nature, particularly in such a blue heavy meta we have currently. (His default Hammer+ works well in the interim too.) Mages will still blow him out of the water, but his movement means he can usually snipe them first, and if you slap Drag Back on him, all the better.
