So I thought about it a while and decided to try a slightly different version:

Grukk's Rippin' Krew
Grukk Face-Rippa/
Skrak's Skull-Nobz
Rustgob's Runts
Kumpa's Killa Kanz

Painmob
Painboy, warbike

Nobs x6, warbikes, 2x PK, 2x Kombi-Skorcha, bosspole

Boyz x 30, 'eavy armor, Nob w/PK&BP

Dreadnought, 2x Skorcha

CaD
Warboss, Bike, PK, lucky stick, bosspole

Zhadsnark 'Da-Rippa' (warlord)

5 Warbikes, nob, pk&bp
3 Warbikes

1850 exactly

This makes the nob bikers a better unit by far, primarily with skilled rider. Also his I4 power fist isn't much to laugh at either.  I do wish I had the painboy in with the 30 'ard boys but the lucky stick makes up for it quite a bit.

Should be a fun list to play, if nothing else!
