Yeah but when I see someone big training martial arts my bet goes that he's doing box, muay thai or eventually some grappling. On Wing Chun I remember seeing 90% people shorter than me that were there because of self defence. I know that it's most probably not a problem for you, it's just that it's hard to picture a big guy on a Wing Chun training with all those finesse moves.
I stopped liking sparrings too recently, I don't know why tho. They always motivated me to train harder but now I prefer "lighter" trainings with more spiritualized things too. They start to relax me better.
We have a huge Copacabana MMA academy here in Warsaw so a Jeet Kune Do school would fit better

Unfortunately our "dojos" have weak standards (they're usually located in elementary school gym halls) and I think it's because martial arts are "cheap" here. 50$ = one month of everyday trainings for one person. There are usually 10-25 people training so there's not much money to earn considering you have to pay the insurance, pay for the "dojo" etc.
Also smaller schools are closing down because people these days want to traing something with Muay thai, Krav maga, MMA or Vale tudo in it's name. That's a strange fashion.
But somehow we have a lot of martial art clubs here, they're just located badly so most of them are rather far from me. Also the quality really varies. If there's about 150 martial art sections here I could recommend only about 40-50. I visited so many terrible clubs with stupid, inexperienced or irresponsible trainers that it's unbelievable.
