I am so glad you brought this up and am excited to play again this year!! It was really fun last year and I enjoyed paying attention to a wide array of scores from different gymnasts.

I think I picked around 80 or so last year and didn't get to the end of my list. (although I don't remember exactly so it could've been more) I wish I would've put more higher ranked people on my list at the top last year because I got to my lesser knowns quicker than I had hoped. 

My other tip would be to pick widely across teams.  If there is a bye week for a team you have to fill in your spots with other gymnasts.
