I have pretty much decided on a Manfrotto 055xpro3 tripod and I am thinking of a Jobu gimbal head. For the mounting plate I was hoping to get an idea from you all on a mounting plate. I was wondering if the nx-2 is right for the Sigma 150-600mm C version? I am not sure if you all have heard of the Jobu company. They are a Canadian company I believe. Thanks for your input. They have a shorter plate as well.. Thanks again
