Insurance Professional Seeking FA Position

As the title says, 10 year insurance (employee benefit/group medical) professional looking to expand in the FA arena.

If you had one chance to make the move over again, what B/D, wirehouse, or other would you go with?

Currently starting the process with ML, MSSB, Ameriprise, and Raymond James.

What ideas, tips, pieces of knowledge, etc. would you give a person in my shoes?

Thanks ahead of time!
