Let  be a topological vector space, and let  be the algebra of continuous linear operators on . The operators  are disjoint hypercyclic if there is  such that the orbit  is dense in . Bès and Peris have shown that if  satisfy the Disjoint Blow-up/Collapse property, then they are disjoint hypercyclic. In a recent paper Bès, Martin, and Sanders, among other things, have characterized disjoint hypercyclic -tuples of weighted shifts in terms of this property. We introduce the Strong Disjoint Blow-up/Collapse property and prove that if  satisfy this new property, then they have a dense linear manifold of disjoint hypercyclic vectors. This allows us to give a partial affirmative answer to one of their questions
