I just got my new Canon 500mm lens for my 30D. I have a tripod but also enjoy using a monopod for wildlife hikes. In the past I have used my ball head (gitzo 1277) on my monopod for my 100-400. I just don't feel as comfortable using that with my 500mm due to the weight. Would it be better to mount a quick release plate right to the monopod and forget the ball head? Any ideas would be appreciated.
