If you’re spending Planet X/Titus/Waltly type money then my advice would be to keep the box it came in, you’ll be needing it before too long.
That's not true, is it? If titanium was so prone to failure that the likes of Planet X had to warranty every frame, they'd soon stop selling them as the economics wouldn't work.
I've been riding ti frames for over 20 years and have never had to warranty any of them.
Selling a bike/frame with a warranty ≠ honouring that warranty.
My real advice would be that if that’s your budget then don’t buy ti but I’m pretty thoroughly embedded in steel bicycles and the industry around them so I’m probably a bit biased.
