As the subject says, when running normally - what is the closest to canon designs do you run? For me, it's likely the GRF-3M. The only tweaks I made to the default build was to remove CASE, add Endo-Steel, upgrade the SLas to a MLas, move the ammo to the feet, and I think bumped up the armour. That's what my memory tells me. I'll have to check when I get home.
I run a Catapult C1 with stock weaponry with upgrades and an xl 300, so not 100% stock by any means. Either way it's a solid weapon load out, and if you can work it you can easily do 600-900 damage provided things go well for you. I average at about 300-400 with this thing of late. Now I also run a thunderbolt with the Thor or Summoner Prime load out. http://mwo.smurfy-net.de/mechlab#i=114&l=a5fd5b687f495da5cfda0884018c5c3c4bd85d12 Its not amazing but oooohhhh the nostalgia.
