Yes, I tried that approach on day one -- unfortunately it did not work because of this message:

So I used ACH transfer from the SAME bank and it worked just fine. BUT while the ACH worked the next day the bitcoins were held up until Wednesday. When I started this --- ripple was .30 and just yesterday it hit .80, waiting might be expensive. Thanks for the advice however.
