I like to run my Mechs (especially light ones) with max armor and max engine. In Spider chasis I like to have max JJs too if possible. 2x MLas / 1x MPLas are nice damage dealers, combined with ECM you are more than able to harras on battlefield. Just beware of 2Ds and 3Ls because you'll be toast if you don't run to safe distance or seek shelter under a friend's DC Atlas or something. ADMIN EDIT: Updated build crib sheet with proper ECM placement.
I also tried to run slightly modified version with 6/8 JJs and AMS plus ton of ammo. AMS really helps to survive SSRMs from those those pesky 3Ls and 2Ds (if you're not too close ofc).
Since dear admin raised this thread from the dead , I'm posting my current build, based on original build from post 1: Lowered left arm armor to be able to install 2 MPLas and 1 MLas, JJs are still 8/8 (all crit slots filled, full tonnage). Heat is bearable, this little guy is flying high and aiming low. hear:
