t-max 3200 / np 1600 pushed in paterson varispeed?

sorry if this is going over old ground, ive done a search but can't

find anything specific. I wondered if anyone could tell me how to

process both fuji np 1600 and kodak tmax 3200 in paterson varispeed.

I would like as big a grain as possible so was hoping to uprate to

6400 or 12800 if possible. any experience with this combination (I

have not pushed/pulled any film before) would be of great help,

especially if specific dev times, temps etc could be given. Thanks

guys. Tom

To the best of my knowledge, Varispeed is no longer made. FX-50 is the current high-speed Paterson product.
