I'd be very curious to hear more about this bar and specifically about where the padding on the actual bar contacts your body. I have a cheap SSB and it's fine for doing what are essentially front squats. Similar to the original poster here, if I hold the handles, my elbows hit my knees but that happens *well* below parallel and kind of acts as a tactile cue for the range of motion.
Most SSBs have straight handles. It appears that the transformer bar has curve handles. This would be a huge improvement because I have to be *very* careful that I don't end up with weight on my cervical spine. Looking at what few pictures are on the website, it seems that the handles are curved in a way that the bar sits lower on your back than an SSB and the issue of stress on your neck would be eliminated.
Also for $600+ you really should bring it inside when you're done lifting!
