Tri-las preds are the bane of all SM players, they can rip trough the armour easily, others on this forum will say dont take them, but i have a lot of success with them over the past couple of months and with all the mech around nowdays your going to nead them 3 las cannon shots. Remember they are more points but you are getting a re-roll on 1 of the hits rolls. Just food for thought, try them out, if they dont work then dont use them.
