6 wheel wide chassis - is there any advantage over just 4 wide?

[VKP]

A wider chassis would definitely be easier to turn, but in this year's game, balance is very important when getting over the barrier and the ramps, and a wide robot would be more susceptible of falling over backwards or forwards over those field elements.

The reason for building a 6wd is so the bot can turn better. So i ask you, how do you make a 4wd turn better?

(the answer is: By adding center wheels(effectively making it a 6wd).)

In 09 a lot of teams went wide and thought that because they are wide turning with 4 wheels will be just as easy as a long 6wd. Yet with a trailer and a lot of heavy defense, wide bots with either swerve drive or 6wd triumphed in turning capabilities and escaping defense.
