I do not have the Elegante yet (but hopefully soon). I was intrigued by these Delugs straps that are priced a bit more reasonably vs. the (let's call it honestly what it is) "overpriced" factory FKM rubber straps. Just based on their website images, I already like the Delugs texture even better/more interesting vs. FP and the fit seems perfect.
IMNSHO, it's REALLY a shame that they did NOT make their strsps fit the factory FP clasps. Should be simple enough from the engineering point of view, but for whatever reason, they changed the dimensions on the clasp-end, so only their proprietary clasps have to be purchase/used.
Nevertheless, I would still consider to purchase a couple....and would greatly appreciate your feedback. Thank you.
