Use Manfrotto Tripod Manfrotto ball with MT055XPRO3 410Junior rack. The set fits perfectly into the bag (ideal size). The bag itself is fine: good protection, good finish ... we can put more foot accessories, very good value when compared to the brand bag. The only "downside" in my opinion for closure "flash" that does not inspire confidence. I think it will be the weak point in time (but this piece will be a nice change with a needle & thread).
