this one is YOUR workout. you can make it what you like. i think the obvious answer is to do it both ways (not in one day!) to keep your body guessing.
most crossfit metcon wods imply minimal rest, so some would say to cut your weight to keep things humming as non-stop as possible.
or, you can set a benchmark by doing it the "easy" way and record your time. each time you do the workout, add to your weight and/or box height. try to match your first time.
why not post this one in the wod board. we have a huge thread going called "new cfpc wods". i think folks would enjoy this one. but you have to come up with a clever name first...which is half the fun.
