Best way to transfer large sum between banks?

[FreeAtLast]

For one time transactions or need a paper audit trail I get a cashier check. When I will be doing it on a recurring basis I set up an ACH money link.

Thank you all for the feedback. I ended up going the wire-transfer route since TD Bank told me a cashier's check could take up to 4 days to clear due to the fact that I have a new account with them and the first 30 days are considered "risk-prone". Fortunately, no questions were asked by BOA and the money appeared in my TD account right away and cleared the next day. I tried to be as friendly as possible about it, and I still had about $20K left in the account, which I will transfer via personal checks made to myself in the near future, once everything else settles.

I appreciate everybody's input!
