However, I did try out eKatherine's instructions this morning. The worst part was going from crouched in front of the wall to feet all the way up - by a long shot. Once my feet were up, I managed to walk my hands back to about 2' from the wall and stay there for 30 sec, so I think my head's going to slow me down more than my arms and shoulders. But thanks to eKatherine and Old School, I'm going for the one-armed shot. Maybe I'll post a pic next year.
You look strong as an ox, Knifegill. Suck it up!
