Replacing existing cast iron DWV with ABS

I'm currently in the middle of a kitchen/bathroom remodel and part of that includes rearranging the bath fixtures from the existing toilet/sink/bath configuration to a sink/toilet/bath arrangement. I'm replacing the entire cast iron/galvanized DWV setup with ABS as that seems to be the path of least resistance. The stack runs through a wall that will have cabinets on both sides with the bottom end located in the crawlspace, so noise should not be an issue. I haven't worked with plastic pipe extensively, the horizontal end of the cast iron runs on a noticeable slope towards the main sewer line, I'm concerned with being able to replicate this slope with plastic pipe. From what I can tell plastic pipe fittings seem to fit perpendicular and tightly to one another without much "slop" to adjust for slope, am I mistaken?

As you cement the fittings, there is some adjustment ability to get the standard 1/4" per foot slope.
