A dodge evasion build will use light armor, which has low resistances but doesn't get hit as often.
The best shield for this type of build will have high thresholds, meaning that most of the damage of the attack is absorbed by the shield.
Leather armor has poor energy resistance, so it would be best to use dual high or medium frequency shield modulators.
If you attach two modulators to your shield, the effects will be cumulative.
The best shield for a high dodge/evasion build is two high quality high/med freq modulators with a high quality power core and a capacity upgrade.
