i have not used the 2000 series reels for a while. I do ten 35mm and 12 of 120 in the 1000ml with absolutely no issues. Kodak's solution capacities can be contradictory but I recall that all but the first developer have twice the capacity of the first. So, it is the only issue. I would be shocked if you noticed a difference. I developed five sheets of 8x10 in an expert drum with the amount set wrong and used 330ml which is like doing five rolls of 35mm in that much and the films looked perfect. I think there is little risk. There is also little to lose by limiting yourself to ten rolls at a time.
