Have tried it many times, Tri-X @ 1600 & 1250 asa - Rodinal 1:100, gentle swirl for 30 sec, stand 30 mins, 30 secs swirl, stand 30 mins.

I can honestly say I have never got consistent results. Rodinal 1:50 for around 18 mins will give you better results.

If you will be regularly pushing Tri-X up to 1250-1600 then Diafine or any two bath will give more consistent results especially for wet printing.

Take it your doing regular agitation on the 1+50 for 18 minutes?
How's the grain?
