***** stars for you, Ben.
I will start DL/Squatting using my Trap bar; by the way, I built it from 4x4 and have been using it for Deadlift & RDL.
I like your closing remark "..even if your knees does not hurt, it is still beneficial to use the Low position DL and Squatting the weight up ...".
Thanks for sharing it with us .
