Very eye-opening, thanks Aimee.
Since I can barely squat my bodyweight, I think I still qualify as a "beginner" and am going to stick with the LBBS for the rest of my current cycle (9 more weeks). I think the limiting factor on my Oly lifts is still mostly technique, so I have some room to improve there before quad strength kills them for me. But after this cycle, I'm thinking I should shelve LBBS in favor of HBBS and Front-squats.
