For Christmas I received a Manfrotto 055XPROB tripod (http://www.bhphotovideo.com/c/product/504845-REG/Manfrotto_055XPROB_055XPROB_Aluminum_Tripod_Legs.html). I was looking around last night on B&H at all of the different heads, but am struggling since there are so many. Any specific ones that you recommend? The main purpose at this point would be for taking macro photos of the tank. Thanks!
