Hello folks. I am pretty much a Karate novice having only a brief stint at World Oyama Karate. So my sparring has been limited to Knockdown Kumite though I also trained at an MMA gym for a while, and have done Judo randori. I am wondering how many of you folks spar with aliveness, full-contact, and continuously (as compared to Sundome or lighter-contact Point Sparring style)? If so, what is your preferred style of sparring both in the dojo and fighting in the arena? And why? Do you think your preferred sparring style is practical for "real world situations"?
