Planning on some STF-Alt char.
I´d definately go for 12/27.
For my Alt, I use the Espada eslavona, and having 9 Athletics is really a plus if you want to play fencing-style.
Once you have 9 Athletics, it´s easy to back up from the fight and run in to stab anytime.Marvellous.
Oh and you will still rarely glance.I dont know why, but I almost never glance on that Alt, even on swings with 4 ps.
