I'm thinking the Alaskan is a composite stock?
Then the Timber stock will be more traditional for Africa and might, look better on the photos.
That's personal choice but you asked. I hired a rifle, I can't cast a vote. I have timber, composite and laminate.
My CZ550 is Timber and would look cooler if it had a barrel band but that is my ideal image of a Safari rifle.
If you are going all traditional with shorts, safari shirt and a Pith Helmet timber stock is in vogue.
If you can love a plastic stock and use it in Africa , go make dreams a reality because it's your preference and your hunt.
If I was hunting foul weather I would take a rifle that suits the part. If you need a composite stock where you live/hunt then it makes sense to by the Alaskan.
