Yeah, you will probably crash and burn once the weight starts getting heavy. I don't see a compelling reason to change the protocol from how I've been using it for like 10+ years. With this program I've had best results with training each lift heavy 1x/week. For some people I program them to do a light squat on their deadlift day. And when I use this program I fill in the trainees volume needs with supplemental and assistance work.
