My 2nd round slow-grow list is due soon, and I'm having a hard time deciding which way to go.

I've narrowed down my choices to the following, and would like an opinion as to which I should take and why.

My current 15pt list is:
eThag
Carnivean
Teraph
Shredder

My choices for 25pt list:

eThag
Typhon
Teraph
Shredder
Stryders+UA

eLylyth
Typhon
Teraph
Striders+UA
Deathstalker
2pts Undecided (Shredder, Harrier, or another Deathstalker)

Thanks in advance for the help
