Opine early on 2015 keepers

[Falcon]

With the 2014 season in the home stretch, looking for opinions from the pen on my pitching-heavy keepers for 2015 in my 10-team, NL-only, 5x5, straight-draft league (no $$ involved):

Sure bets:
Stanton
Kemp (if not traded)
Holliday
Heyward
Revere

Hamels (if not traded)
Rosenthal
Kimbrel

With two more spot available, need to choose among:

Arrieta
Cashner
Roark
de Grom
Benoit
Syndergaard
Gennett
(Told you I was pitching heavy)

My trade options could be limited because the league tends to heavy favor position players over pitchers when it come to keepers.

Thoughts from the Pen?

Arrieta, Cashner, de Grom and Roark are all pretty even for my tastes.

I would rank them:

Arrieta
de Grom
Cashner
Roark

But all four are solid.
