I use Rodinal for developing all my film, I use alot of Fomapan or TriX, i am venturing into using Ilford FP4 and am thinking of shooting it at 80asa and dev. For 9 minutes at 1:50. Would this be a good start? This is for printing in darkroom with 120 negs. Thanks.
If you haven't shot a film before, IMO the best place to start is the manufacturer's data sheet. Ilford's sheet https://www.ilfordphoto.com/amfile/file/download/file/1919/product/686/ says it's good for EI 125 in Rodinal 1+50 for 15 minutes. Is there a specific reason you want to shoot it at EI 80?
FP4+ is gorgeous in Rodinal at EI64.
If you use 1:50, that's good both for overcast and sunny scenes.
20C with 2 inversions in the beginning, and 2 inversions every minute.
8-10 minutes depending on your enlarger.

Anton: Pieter's recipe (and dilution) looks fine for soft light. An option if you don't seek direct sunlight.
If in the future you use FP4+ in MF and 35mm, EI64 is great for Perceptol 1+2: sharp grain as with Rodinal, but smaller and tighter. And middle grays are brighter, not depressed. Fine detail is better too IMO.
Anton,
I have used Tetenal Ultrafin and FP4 with good results (EI 100), but Rodinal 1+49 should also work well - suspect your intentions of 64/80 EI are sensible.

The recommended film for a Brownie Hawkeye back in the day was Verichrome Pan, and FP4+ is the closest there is (in terms of film speed, anyway) in today's market to that lost and lamented gem of the 1950s. I'd recommend using the Massive Dev Chart listing for either 1:25 or 1:50 dilution of your Rodinal. Given the negatives are 6x6, you needn't worry much about grain (FP4+ doesn't have bad grain in Rodinal, even in 35mm, in my limited experience). Once you have the negatives processed, you can make a decision whether to adjust your development time.
