Buka.... that made me laugh...
Who remembers the pic (probably more than one) of Master Hee Il Cho nailing the canvas hanging heavy bag with the jump-spinning side kick and the filling just exploding out the other side... NICE! Talk about a dude to want to emulate... That bag was probably a 60-80 lb bag and he was just destroying it.... Awesome!
On point-fighting. It is specialized tag,and no more. If you practice all the time, and your goal is simply to get good at point-fighting, no worries, go for it. Just don't be deluded, as such delusions are dangerous, both to you and to people who you might think you can protect.
If you think it is actually karate, and valid as a self defense skillset, or fighting method, I would nvite you to look up the next Kyokushin and try out said skillset there, in that venue. I can absolutely promise you that you will find it... educational.
As with other things in life, training full-power has it's place. Everything in moderation. Put on the big pads, complete head protection, perhaps even some rib protection, hand and footgear, and get after it. Just be prepared to feel sore as heck the next day, if you were doing it right with someone close to your own skill level.
But, don't train that way every day, either. You can lose a month or more if you crack a single rib, and that happens Easy. The loss in training time from injuries costs much more than simply cycling it up and down.
