I have involved earlier in the work while designing the t-shirt for the nepalese association. Like here, we sought the input from all the people of the association. What I have realized that people usually like the simple and easily understandable to non-nepalese also. They usually want the blue and red color seen through it which are the color of our flag. I would go for first logo (if possible with red and blue color). As obama suggested, big logos do not look good.
Thanks
