I'm thinking about trying out Krav later this year for some cross-training, and there are two places that fit my schedule; one place is affiliated with IKMF and the other is a Krav Maga Worldwide school. I'm planning on visiting both schools, but before I do that I did have some questions. I've done a little research online, and IKMF sounds like it might be a bit more serious/reputable, while KMWW seems a little more business-oriented. Is that the case? Are there any other major differences between these groups, in terms of material, training, etc? I know some of what I'm asking about is going to depend on the instructors and school culture, but if you guys have any relevant tips/wisdom/advice, I'd appreciate it. Also, regardless of org, is there anything in particular I should be looking for in terms of what's "good Krav"? Thanks!
