I am in a half arse keeper league, where you keep 3 players.  The prior years draft value of your keepers affects the draft round you lose for keeping the player.  I am keeping Pujols and Weeks, but can't decide between Aramis Ramirez, Vernon Wells, and Johnny Gomes.  
If I keep Ramirez I give up 3 early rounds.  Wells - 3 early/middle rounds.
Gomes three late rounds.
One scores points in the usual counting offensive stats.  Strikeouts hurt, but not that much.  14 teams and all are reasonably savy.
Any advice?  

Who are some age-relative-to-league prospects that panned out?  
It seems like this is the weakest prospect characteristic and I would like some more thoughts on the subject.  Hidalgo had one great year.  We have covered Rivas.  I don't think Beltre counts because he put up big minor league numbers (even though he only had 350 minor league at bats).
