Alex, I thought the Kentona was a grade 3, they only call it 2 in England. LEaving it in longer, up to 4 mins, is supposed to give you more contrast. I solved the problem, btw, it just needed more development.
Well, we all know there's lots of slop in the grade numbers. Comparing it to all the other papers I use or have used, I just can't seem to get it beyond about 2.5 even with extended development. I think Kentmere would have a real winner if they brought back a grade 3.
