Help choosing SubLBs

My four safeties are Eric Berry, Poyer, Bates III, and Julius Peppers.

Have been running  Berry and Bates at SubLB, Poyer deep SS, and Peppers deep FS bc my 50/50 GB TT gives him enough speed and acceleration boosts to be able to play up top still, but his PRC and AWR ratings are atrocious (87 & 88), so while CPU controlled he can go braindead.

Thinking about making Peppers my exclusive user in the box to counter the low PRC/AWR. Can’t decide who to put up top FS and who to keep at SubLB between Bates and Berry though. 
 

Another thing I’m contemplating is switching my defensive strat card from Slot Specialist to Mind Reader (+4 PRC, +4 AWR, +1 TAK for MLB/Safeties) because 

A.) Pretty much all of my DBs meet the coverage thresholds without the Slot Specialist boosts already

B.) Peppers would hit the 91 thresholds for PRC/AWR, albeit they would still be low ratings at 91 & 92 and don’t know if that would make enough of a difference to justify keeping him up top

Any insights would be awesome!

I also have a GB TT and play Peppers exclusively up top and he’s a menace. my two SubLBs are Jaylon Smith (who has 98 speed on A full TT) and Poyer with Acrobat. Peppers’ PRC doesn’t seem to be a problem for me cause he jumps routes and Mosses people on jumó balls all the time. I’d keep Berry and Peppers deep with the other two inside but that’s just me

I would put Bates uptop and Peppers inside. Bates is more coverage and Peppers is just taller inside
