In a large bowl, mix the lime, fish sauce and sugar well. Break up the lime segments. Toss with sprouts and basil. Check for seasoning. Lay out 1 rice paper wrapper and place a small mound of salad at the bottom. Top with lobster and mango. Roll bottom toward the middle. Fold in both sides and continue rolling. Finish roll and let rest. Individually wrap each roll with plastic wrap. Will hold for 2 hours in the refrigerator. Slice on the bias and serve on top of extra salad.
