formation help please: Dea skill vs higher overall stats

Ok, so need some formation advice....
Current formation is:

Lotus+ (IPD)
Adan+ (hp up)
Manu+ (IPA)
Carnage+(creation down)
DBE+(dea)

Bp= 154 // atk= 78913 // def= 74935 // Hp= 91903

I Originally had a mix guild creation team, but with the new combos found that it is much better to have mix species with impulse combo, so i started switching by trading manu for nyar....

Now I have an Ozwiiga+ and need to decide whether i should do 1 of 3 things,
1. swap out carnage ( this will give me all good skills, but lose out on stats)
2. swap out DBE (this will give me better stats, but i no longer have dea)
3. keep DBE in def form, but swap it out in ATK form.


If i swap out my carnage this is how my form stats would look:

Bp= 144 // Atk= 80924 // Def= 69574 // Hp= 87842

If i swap out DBE:

BP= 152 // Atk=94095 // Def= 80297 // HP= 90380

.

Big Question: Is it better to swap my carnage(creation down) or DBE(dea) for Ozwiiga(ded), or even just use Ozwiiga for when i attack?

*note: anyone know of a cheapish AA+ Sin monster with DEA above 25bp ?

Thx for imput, and putting up with me ^^

Dea is pretty important, Maybe just swap DBE with Oz when attacking but you're gonna want dea in your defense form for sure
