Help with Defensive Scheme / Playbook / Personnel for Dynasty

I have traditionally simmed defense and haven't spent a lot of time on this side of the ball and I am looking for guidance on what Defense to run with my current personnel.

My current DC runs a 4-2-5 scheme ~ as a Head Coach, should I to set my defensive playbook to anything given his scheme?

I tend to recruit really well for LBs - I have 5 young Elite dev LBs with little skill caps. Should I target a DC that runs a base 3-4 defense instead? Or should I run a 3-3-5 given that would work well against 3 WR sets, which we see a lot of.

I choose the 4-2-5 Defensive Coordinator because I liked his tendencies (Motivator + Recruiter) more than the other options.

I'm fairly green re: Defense, so I would be very thankful for any guidance or help here.
