Now that there was talk on uke's pain from the hacks.
Don't hackers hurt themselves too?
I used to be a hacker but stopped because I not only pissed people off but my feet don't like to be used as hockey sticks.
I now resort to the cup and lift like a sticky foot kosotogari.
I think the spirit of cooperation is what we need. If you go against somebody and you see they are wearing shin pads, help them out and test the pads to make sure they are working.
Sometimes the adults are put with the kids for randori to give them an extra workout and tougher opponents, these are the days when my shins are bruised beyond belief. The kids just walk up and soccer kick your shins thinking they are doing a throw. Its is especially bad with unclipped toenails.
