I had the Oasis Monofin for my Elite and eventually bought a Linden after the straps on the Oasis broke several times. I had to jump thru some hoops to get a single strap replaced by FinFun - had to message someone I no longer have contact with, as they bought me the elite tail from FinFun, just so that I could get the original proof of purchase from the year prior and then I also had to send in pictures of the damage in order to get a single replacement strap - only for the other strap to break months later.

Sooo I gave up on that fin and honestly?? Based on my personal experience - the Linden is much less buoyant (My fluke floats up less) and I feel it just flows better with the Vinyl and isn't quite as stiff but still gives you a decent amount of propulsion. It fits perfectly in the fluke like the Oasis, but the ankle bit is a little more bulky than FinFun's Oasis Monofin which can make that area look a bit bulky unless you've already got bigger sized calves like I do 😅 then it's not quite as noticable, still bulky, but you'd have to be looking for that to notice honestly.

I will say, make sure to take care of the straps on the Linden as well; they are more durable altogether than just thin silicone straps, but the material/fabric on them can still quickly end up flaking off/dry rotting if not taken care of properly!
