I'm not Andy, but you're right in that it's a bad idea to try and predict which lift will stall first. Who knows, your bench could be going fine now and it could hit a hard wall next week while your squat continues to go up for another 3-4 weeks.
If your squat does stall and you want to switch squat programming to HLM, go ahead, and keep the same schedule for everything else, assuming you're doing a 3x/week LP on the other lifts.
Also, how tall are you? 183 pounds could be just right if you're like 5'6", but severely underweight for strength if you're 6'3".
