Umbrella refl

I am getting ready to buy two umbrellas for my Lund. Everyone on the board seems to think that the Sports Brella is the best, I think. I have talked with Gene about his new umbrella, but he has no dea when it will be available. So, I am preparing to buy something. My question is this:
If the Sports Brella has a silver colored under surface, what problem are y'all having with reflection off the water. I have had numerous basal and squamous cell carcinomas, and am awaiting a biopsy report of a potential melanoma. I wear a wide brim hat, gloves and a long sleeve fishing shirt. The last thing I want is reflection off the water, which can be just as bad as direct sun's rays. Your experiences would be appreciated.

That underside is a dull or matte finish silver and I don't think it's gonna be much of a reflection problem. I have never noticed it being a problem anyway.
