Need opinions!

So my husband and I plan to use my BIL's initials if we have a boy. The initials are T.D, well he also wants to use his middle name, but I do not like the name. So, I'm trying to get him to agree to use my dad's first name as the baby's middle name. Same initials, still would be T.D. What should we do? Should we use my BIL's middle name as well or should we go with my dad's name?

Also, let me know which name you think sounds better.

David or Daniel.

I do not want to give away the baby's full name.

I really hope this isn't confusing!
