you know the frog hop or bunny hop. this is chatty area so i hope i'm okay here. hopping underwater after you sink on an exhale/empty lung dive. seeing how many times you can. i saw a video about it on another thread but he wasn't competitively hopping just dealing with co2 which is great but what about seeing who can hop farther etc.? at easter they should have a hopping party in the water with everyone dressed as bunny rabbits or frogs! i don't know how informative this is but its the beach bar and all:chatup
