Fomabrome 123 is supposed to have a similar surface, accordingo the Ag website... Never used it myself.
Personally I miss the huge range of sizes that Kentmere made. I liked their square paper, since I have a lot of 6 x 6 cameras. I still have boxes of 10 x 10" Bromide.
Alas.... No longer available.
But I suppose this is the price we pay for a healthier Harman? At least some of the Kentmere range is still with us.
