That is easily within Ground’s abilities to ship reliably. Especially triple boxed, and (I presume) with an inner closed-cell polyethylene foam cradle (the best cushion at this weight class), and with the appropriate insured value. Added up, that’s already all over-the-top security. And I imagine the freight costs would be be very, very high. I’d ship it Ground and sleep great for the next 2 - 5 nights.
Most (not all) of the people with Ground horror stories simply don’t know how to pack worth a god damn. The real high-end makers like Esoteric, VAC, etc - they’ll include the best packing with their products. They can’t afford to have losses in transit, even with insurance.
That closed-cell foam stuff is godsent. Customizable, endlessly reusable. SO much better than that horrible polystyrene foam everything used to ship in.
