Okay, I tried it last night at considerably less than 380. It could be I need some coaching in it, but I ended up preferring the "slow lift" version from SS. Hard to rest the bar on the deltoids without shrugging the shoulders forward, resulting in elbows way forward of the bar. Squeezing the elbows back to get a vertical forearm put the bar closer towards my fingers, which had to weaken the drive. Perhaps a wider grip was called for (long arms but forearms are in proportion to upper arms). I could certainly get the "pop" of the bar off the shoulders with that first move, I just couldn't extend the arms enough under it to take advantage of the pop.
Two sets of 3 reps at my PR, went back to the slow version (with a lot more initial lean) and squeezed out 4 reps.
