i picked up what i think is a decent tripod (manfrotto 190xprol) but im not to keen on the head that came with it(804rc2) .its is a bit of a pain to adjust with the 3 separate knobs .is there something better that doesnt cost as much as a lens ? i mostly shoot wildlife with my 100-400 lens .i have seen a few posts that recomend gimbal hears bt i cant afford one right now.
