Got me some work to do!

We are embarking on a similar project but not going the see-through route you chose and trying to rip out the floor from the inside leaving the membrane underneath intact. What kind of tool did you use to rip out the plywood? We are using a mallet and crowbar at this point, but it is slow going. Thanks for the inspirational pictures as we start on this messy project, the plywood looks great! What type of floor are you putting in on top - sheet vinyl?
