I am about to shoot some 5x7 Arista Ultra 200 at 100. Previously I have developed it in Rondinal 1:25 at 68 in a JOBO for 4:15 with good results. But for simplicity I would prefer to use Ilford DDX or Clayton 76. Any suggestions about starting times for developing Arista Ultra 200 at 100 in either Ilford DDX or Clayton 76 would be appreciated. Thanks
