please, talk to me about robot drive

sure figuring out gear ratios, max pushing power, current pull and such was pretty easy, but setting up some wheels to do the job.. not so much. I have been trying to research some drive designs but seem to be hitting a brick wall in my progress. to make this easier to read here's just a list of design ideas. PLease comment slash ad!
-6 WD - saw design with all traction wheels all wheel contacts coplaner
-6 WD - Drop center, all traction we prototyped this and found it near impossible to turn while stationary. The center axle was dropped 3 washers (french national measurment, its real look it up..) which was about 3/16" i believe
-8 WD with some funky mechanism that lifts the front, and rear wheels off of the ground as to shorten the wheel base.
-6 Wheel swerve where the front and rear wheels move up to 80 deg. (view mars rover)
-6 WD coplaner- middle and rear traction, front omnis <-(prbly will proto type this withing the weekend)

thank you for any input. We are looking to have a strong stance on the field, so in any design some amount of tractionwheel is desired.
