In case this helps anyone else, here's my XP usage...

I dropped the ball a bit on:

1) Raising SET for L-Moyer (nice to have)

2) Raising DEF for S-Clark (more than nice to have)

3) Raising SRV/DEF for RS-Delgado (Prioritized Freshman more and have an A- Senior that needed to play)

Overall, I left some skill raising "on the table" as they say, but not too much.
