I think Groh's 1A is meant to serve a very specific purpose, much like Zas's, where it's kinda crap outside of SC but once you enter SC you now have an exceptional low. Can't figure out why they made Groh's so slow though. On a more positive note, his SC 1BB into ID looks like a very advantageous stance transition even on block.
Also, I can't find the video where I saw it but I could swear I saw someone charge ID A (low spin). Can anyone confirm?
