Although I am from Kyokushin, I can't help but see some similarities between our systems. Our particular style of Karate make heavy use of our shins as weapons. We also will block (catch) incoming roundhouse kicks with our upper shins (very similiar to your Low Kick Destroyer). We don't typically use shin guards, relying very heavily on control. There is also the conditioning of shins, forearms, etc. That being said, no one bats an eye if someone is using shinpads during training. Our instructor is a very pragmatic man. The last thing he wants is for one of his students to be limping around at work or school the next day. Don't get me wrong, we still have our fair share of bumps and bruises. That is how I started following Sylvie (How to treat damaged shins). In general, there is really nothing wrong with training w/o shin pads AS LONG AS you are sensible and responsible about it.
BTW- I don't see any mention of treating shins with Dit Da Jow. My acupuncturist make some for me and I was shocked at how effective it was.
