Hi, I use a manfrotto tripod - model 055 xprob with center column. I had a manfrotto 490 ballhead and switched to arca swiss monoball z1 sp. The manfrotto ballhead , is much taller , though having lower load capacity. While shooting photos, I sometimes find the manfrotto tripod to be little short , with the arca swiss ballhead. I am raising the center column of the tripod. Is this a good idea?
