My choice has been a doble in 458 and a 375H&H bolt. This choice has worked very well. I might prefer a 375 double, but I don't own one so the issue is - currently - moot.

Vilignius, your Botswana outfitter was just plain wrong. If the light double was unscoped then perhaps the big double and a scoped 375H&H but no reason to leave the big double home. There is more and more demand for double rifles for many reasons, not the least of which is that they are excellent choices for DG and far and away the best choice for elephants. Teamed with a suitable scoped rifle or detatchable scope for the occasional longer shot, best option there is.
