Depends on what you're interested in. If international, especially Africa and Europe, I'd chose SCI and DSC in that order. If sheep, I'd probably add Sheep Show to the mix and if more North American focused the Western Hunting Expo in Utah.
This may or may not interest you, but you can order one from Europe. I ordered an 8x56 when they were $700. It took a couple months, but it arrived and works great.

I'll second the fewer connections the better. Connections are where luggage gets lost. I suggest putting an Air Tag in your checked bags so you'll know where they're at.
I have two Mauser Type Bs. The first is an 8x57 (.318 bore) with double set triggers from 1904 and the second an 7x57 from 1914. Both are all original and unmolested. The first is actually in Jon Speed’s book on Mausers.
Just to set the stage, I have been a hunter for more than twenty years and incredibly fortunate to take animals all over the world. Almost all of those animals were taken with a rifle. I have been shooting my bow for more than a decade, but it has never been my primary focus until this year...
I just wear comfortable tennis shoes or light hiking boots. I second the recommendation on going without any sort of waterproof lining. And whatever you get, you want something quiet. Some people like these little leather gaiters if they're wearing low cut shoes, but I haven't found them...
Just this past October I missed an ibex in Spain with a Swarovski Z8. It was shooting at least 24” high. This was on a loaner rifle and the scope was set up with a ballistic turret. The best I can tell is that the scope was dialed a lot and completely lost the ability to hold vertical elevation.
