Tirreggregars

I will be using the overall best weapons which in addition drain energy. For example dissolver is useless but drains the most
 
1. Valiant Sniper (17 res drain)
2. Bunker Shell (13 res drain)
3. Piercing Fox (10 res drain)
4. Lightning Cutter (10 res drain)
5. Brightroar (9 res drain)
6. Lightning Recoiler (10 res drain)
7. Bulldog (10 res drain)
8. Ultra Bright (5 res drain)
9. Party Crasher (5 res drain)
10. Frantic Lighning (10 res drain)
 
This is the order which I would use if I wanted to put an eng res drain weapon on my mech.
