Well you're wrong the best is berail gun metalcrush saverclaw jumping shoes and explosion+2 explosion+1 the jumping shos increase the distance of the metalcrush if you use it at the right time
Explosion+1 I mean
Fixed that for you.
And I also agree that's probably the most effective set with the Bearail Gun
For the Grenader, all the same, except instead of Explosives +1, Armour +2 or Ammo +2 would probably be the most effective. Speed isn't really a highlight of the Assault Class.
What do you think?
