75mg isn't enough for much of anything. You're pretty light, though.. I went with 240mg my first time when I weighed about that much. That's what I'd recommend. We threw shit and did cartwheels and played video games and stared at blacklight posters and tripped out from Windows Media Player and ate all my friend's neighbor's food. Awesome for physical activities. Have fun paintballing.. I haven't had the privilege. Laser tag's bomb, though.
