If I am reading the manga, can I skip El Baile de la Muerte if I watched Roberta's Blood Trail? I watched Black Lagoon looooooong time ago, and I am planning to read the manga, since I recently heard that it's ongoing (I thought that manga ended with Roberta, and back then I was not that much into manga).  
I disliked Roberta's Blood Trail OVA, and heard it is even worse in manga form. Can I skip it without losing anything important?
