If anyone is going to bjj or judo looking for striking they're stupid. In todays martial world, anyone halfway serious knows this. Someone who already has a striking foundation, Imo, can make better use out of judo in real life, if you live in a part of the world where staying on your feet in a fight makes the most sense. The vast majority of people wear clothes where I live. Likewise due to the climate, for the majority of the year, they are wearing heavier clothing.
