depends on your vehicle, but 5-link or 3-link with a panhard is the only way to get neutral steering without relay rods and idler arms and other
stuff.
edit: added another option
Which link setup

A five link setup would work the best in the front . The problems you would have with the three and four link setups would not make them worth while. The four link would be very unstable in side to side movent as they dont usually run a panhard rod to centralise the diff. The three link would use an A-frame or similar and you could have problems with the the third link not mounting low enough to aviod hitting the engine or driveline on travell. Hope this helps

Depends on vehicle, budget or fabrication capability and purpose... (is it going to be registered?)
A three link is easiest - just copy a front setup from a Patrol (or 80 series?), the disadvantage is less flex than a five link and a change in castor relative to the length of the link.
The five link is the most flexible in design - you can model all sorts of geometry changes with link mounting heights and lengths, but an equal length setup similar to Wendles is a good start.
With the 3 and 5 links you can make the roll centre changes easily by changing the panhard rod centreline height etc. Keep the roll axis parallel to the ground to provide neutral steer...
What about dual A arms... I just saw a write up on a A arm F250 with 22 inches of front travel (and a four link 38inch rear!!)... mmm...

Either a five link or a four link in a double a frame style setup.
If the four link is setup properly you won't get axle steer or bump steer and will flex better not having a panhard rod.
