@derekkite is using it with the Sigma 500, considerably more weight than the 55-300, so you should be just fine. As mentioned above, they're designed to hold over 200 pounds.

It will "work", but it depends on what you're trying to accomplish. The leash was their first product meant to improve on standard neck straps. Then they came out with the slide(s). The leash is minimalist (lacking the quick-adjusts) and is smaller, lighter, longer, etc. and less comfortable, due to its narrow width.
