Yeah I understand what you are saying as the SSB mimics a front squat due to how the weights are in front of you creating a torque that wants to force your upper torso to fold over. Or something like that.
I've found my weights to be similar with the SSB which is weird.
After heavy training on the SSB for months with occasional breaks for the bow or camber bar, I found I had to focus on getting my butt further back and accept more lean angle with the bow and straight bars. But once dialed in my squat numbers rocketed upward in this past year.
Too many variables to tell whether it was due to the SSB. . . but I think a heavy dose of that bar helped address some deficiencies in my standard back squat.
