SM2: Need help deciding what parent chapter I should choose for Assault and Tac.

Sorry if this isn’t the place to ask but idk like some help deciding on a parent chapter for my deathwatch assault and tac, I can’t decide which one should be a blood angel and if I should do a successor chapter of BA or norm BA

Also need suggestions on what I should make the other class that’s not BA, I don’t like all members of my kill team being from the same parenthood so if tac becomes ba I need something for assault and vice versa.

Also also in case anyone was wondering my kill team minus these 2 include a Mortifactor (Vanguard), a Black Templar (Bulwark bc ofc), a Raven Guard/Raptors (Sniper) I like switching between the 2 sometimes, and lastly a Dark Kraken (Heavy)
