A good blockfactor for 6250 bpi tapes?

[Robert Claeson]

I generally use blockfactor 20 when I'm reading and writing
1600 bpi tapes, but I haven't found a good blockfactor for
6250 bpi tapes yet. The speed seems to be much lower at the
higher (6250) density with a blockfactor of 20, and it doesn't
improve much with higher factors (I've tried up to 128).

If anyone uses a blockfactor that gives good performance at
6250 bpi, I'd really like to know what it is. Please reply
via e-mail.
