I don't think, that AMS is really viable, if you decide to go Scouting at max.Speed. Of course you can use it to protect your mates from incoming missiles, but are you really sure you want to stick with the slow Mechs??? Alternate "AMS" Version: Blagg
I think that this is the best build you can use in this variant. With Speed Tweak, you can outrun or catch all other lights und take their legs. Against heavier mechs, you are fast enough to avoid their guns and you have enough power for taking them down slowly.
If you want an AMS version to stick with the slow guys, mind as well use a 3M and a slower engine of XL180. Better AMS.
