Need advice on waterfeatur and fiber optics

New member. Very helpful forum! We are in the planning stage of an IG pool and are excited, and are thinking of having a Sheer Descent waterfall.(Under a bridge over the pool)
Two questions:
What are the pros and cons of fiber optics lighting for the waterfall? My PB is trying to discourage me from it, because it's unreliable and expensive at what it does. It this true? How much $ should we expect for a 6 feet wide fiber optics for the waterfall?
Any body have any experience , or photos with Sheer CURTAIN (vs . Descent)? We like a "clear sheet of water" look, and some pictures of Sheer Descent the water showed ridges as it comes out of the lip. Having hard time finding photos of Sheer Curtain.
Thanks a bunch for your input :)

I like the fiber optics mixed into the waterfall. I don't like fiber optic illuminated sheer descents. I've been dissapointed with every fiber optic decent that I've ever installed.
I'd have to side with your builder on this.

See ya,
Kelly
