I've been shooting APX 100 and APX 400 in roll film for quite a while and I really like like them both. I have been using the Ilford equivilant to HC110 (Ilfotec) at dil.B and sometimes Ilfosol S and have had good results with both. I shoot the 100 at 64 and the 400 at 200 after having done a bit of testing.
