you can't unlock everything.. and it'll always be a crapshoot..
but there are things to look for..
triple 90s for example (90s in dura/physi and size for example)
or my favorite category... LEARNING.. high learning=steal
but yea.. even if you unlock it and can make good choices which i do..
it still boils down to..
who do you pick?
A B C D if everything is equal...
my problem is i want them all, LOL i see that clock ticking under 1 minute and i'm like ohhh crap
