Hi , Initially I wanted to do Krav Maga, but do to transport I can't do that so have decided to go with JKD. There are 4 places near me that do it: http://www.kick-fit.co.uk/jeetkunedo.aspx http://www.kick-fit.co.uk/selfdefence.aspx http://realjeetkunedo.com/About.html http://www.nottinghamjeetkunedo.org.uk/index.php I have no idea which would be best for self-defence, I'm not too bothered about how authentic things are, but more whether they deal with knives/multiple attackers/getting out of chokes etc. Cheers!
I don't know if Stoke is too far a drive for you, but if not, I would strongly recommend Dave Carnell http://www.impactfightingarts.co.uk/#/dave-carnell/4545783050
Without getting too much into it I would go to the first gym -"kick fit" - which offers an impressive FMA lineage alongside the JKD and should satisfy your requirement for knives etc very well. Out of the othe two, both are Lamar Davis affiliated. I would take the latter of those two because he is the senior rep
