WebTrypsin will cleave after Arginine and Lysine. So setting strictly trypsin is enough as it covers both the amino acids. Primary reason people add LysC into the search settings is because LysC is not inhibited when a proline is next to a Lysine residue while Trypsin is. For some search software, this is built into the Trypsin cleavage rules.
