Dimas has a huge front squat and he did not have a Squat Jerk, he has a Power Jerk and sometimes rides it down deeper. Look at his lifts in his early years he did not ride them down much as he was uber f0cking strong. Later on he kept going a bit lower due to the heavier weights.
In an iron mind video of the training Halls you see Dimas do some split jerks! I think I heard from somewhere that Dimas hurt his foot and he did Power Jerks instead. Probably just BS but I heard it from somewhere.
You need a huge squat to make it affective and a lot of balance. You got to come up again from deep with a weight over head for 3 C&J's that you didn't have to if you could split. Recovery is slim to none on a Squat Jerk.
It looks totally bad ass though
