Xtol 1+1 works great to tame the Foma grain and make up for some of its poor speed. You will need a slightly longer development if you pre-rinse, which you should. I find that if you take the published non-rotary Xtol time and apply it for rotary development with a pre-rinse, it will be pretty close and you can tweak to your content from there.
Don't rotary process with Xtol at higher dilutions than 1+1. You must use distilled or bottled water to make up the stock; the iron in tap-water will kill Xtol in a couple of days - at least it does in Adelaide. You can also make the bag up to 4L instead of 5L which means it has a little less oxygen in it and will theoretically keep a little better; just remember to do 80+120mL instead of 100+100mL to make up your working solution. Store the stock in a mylar bag, i.e. 10L silver-bag-in-box water carton, the same carton you used to make up the stock.
