I have done heavy assistance work before while on 531 and I found it burnt me out prematurely and thus I could not complete as many cycles as I wanted to. I just didn't find the bang for the buck was there - meaning I didn't feel doing heavier assistance increased my core lifts as much as being able to complete more cycles would have.
