Snotlings vs Skaven, what inducements would you take?

Playing against a pretty beat up skaven team in league play and trying to determine what the best inducements would be to take against them. I have 440k petty cash plus 50k from the Treasury to spend.

They have 2 gutter runners with block, 2 blitzers, 1 thrower then 6 linemen. My Team is at full strength with 2 trolls, 2 Pump Wagons, a stilty runner and then 9-10 linemen pending star players.

Thoughts were to take Ripper for 250k. The question is to take Riotous Rookies for 150k or Skitter for 170k to try and catch their gutter runners as I can stab them since blodge can be hard to beat? Another option could be to take a flinga in hopes of getting a good bomb throw and dropping the gutter runners to the ground to foul out of the game.
