APX100 is a gret loss in 5x4. I love the 120 simply because of wonderful tonality. I have used Efke PL100 in 5x4 and it is quite grainy, but truly beautiful. I am going 10x8 and will use this exclusively probably. FP4 is a super alrounder, but I will try Delta 100 having been disappointed with TMAX100 in 5x4. Only trouble is only TMAX100 and Acros are available in quickload and acros is ridiculously expensive.
