Thanks all!
I answered on behalf of my students, who are all recreational skaters. I was very honest, saying their choices are more influenced by appearance than technical features, their parents by $$ and I by quality.
Christy - I think it'll be a random draw. The real question is what will you do with the top-end blades if you win?
Interesting that Wilson and MK stopped their monthly Facebook giveaways. The prize might be a pair of blades from those brands. (Just a guess, no insider info.)
I forgot to give credit for this: I found out about it via a promotional email from the PSA.
