I agree. From my lab notes, I'd suggest ISO 100 or 125 (TTL and TTF
[through the filter], integral metering) for a Wratten #25. Development
as recommended by MACO (XTOL 1:3 14,0 min). 
You may also use the tables on the XTOL data sheet (available on Kodak's
homepage) to calculate dev. times for stronger solutions (1:1, 1:0).
Personally I didn't get very happy with highly diluted XTOL (results
were somewhat unpredictable...).

BTW, a Wratten #25 won't give you real IR effects. Your pics will almost
look like normal bw. Don't know if you really want that ;-)....
