Reflector question

[akiwi]

I posted this yesterday, but possibly in the wrong section. I'll try here.

I have an outdoor shoot next Tuesday, and am thinking of getting a reflector or two. Probably a 5 in 1 jobbie.
For people pictures is Bigger better.
Here is a link to what I might buy 71 x 112 cm

Should I consider buying two of the big ones, and using one as a sun shade for shots in direct light?

I have an outdoor shoot next Tuesday, One person? A group? Will you have help to hold them? Will it be windy?
Sometimes I just use a 30X40" white art board for fill. It works for me, but someone has to hold it unless you want to carry around a stand & sand bags.
