35 Whelen if you enjoy America.
9.3 if you enjoy Africa.

In practical terms, the middle ground of both is the same. But the 9.3 can be loaded truly "bigger" if you want, while the Whelen can more easily be loaded "smaller" if you chose.

The Whelen certainly has more of the cool Americana factor. Just read some of the stories by/about Townsend Whelen--it'll make you want one for sure. Stories about Otto Bock, not so much, as I don't know that there are any.

Or you could be practical and just use your existing 338.
