I appreciate the feedback - I may change it, adding in Deff Coptas and Lootas and dropping the Wagons and Buggies.
Buggies and DeffCoptas - I like the buggies more because of the leadership thing and they benefit from the
KFF without having to zip around if my opponent makes me go second.
Wagons and Lootas - this is the most contentious swap. Lootas are
SA-weet! I dont like their leadership and that Ill be leaving them behind. And more often than not - Ill be screening their shots anyways. The wagons have the same problem but in reverse. I wont be leaving them behind instead Ill be chasing them. I like that better.
Gaz is in the list to help mitigate the accordian effect with a 6 inch WAAAGH! At the end of turn 2 I should be charging - turn 3 definitely.
Turn one the wagon moves 12, the kans move 6 and run 1 to 6 inches. Still within the
KFF 
Turn 2 it gets tricky, Ill move the Kans 6 - at a minimum Ive moved them 13inches - max 18 inches, the wagon has moved 12. I can move the wagons somewhere between 6 and 12 inches and still have the Kans under the
KFF. Lets say I move them 6 for a total of 18inches of movement. If you count the 6 to 12 inches I deployed onto the table - the wagons are about 30inches into the board. The Kans are about 26 inches into the board assuming I rolled a one for both run moves. The boys are about the same (some of them may have to spill around the edges of the Kans due to run moves. For the Boyz - Ill assume a roll of a one first turn and a full 6 inch move on the second due to Gaz's WAAAGH!
12 inch deployment plus 6 move plus 1 run plus 6 move plus 6 WAAAGH plus 6 charge. 37 inch minimum 42 maximim threat range turn two walking. This leaves 6 to 11 inches - plenty of room if the opponent backs into his table edge. If he does - great, less options for them.
The Wagons deploy 12 move 12 move 6. Nobz and Gaz dismount 2 inches WAAAGH for 6 then charge for 6 - 44 inches total turn 2 with only going 6 inches turn 2 in the movement phase.
The hard part will be not shooting with the Kans the fist two turns - the buggies will plaze away the first two turns.
For a coordinated impact into his lines on turn two -
Id have a threat range of about 39 inches for my table edge leaving him in 8 to 9 inches of his DZ. Less considering the wagons will be used to hit those hard to reach places because of the additional movement they offer.
