I'm still learning but I am coming to the conclusion that I want the following: a low center of gravity, good approach, rampover and departure angles and traction through good tires, lockers (certainly a front one helps deal with the foibles of the IFS) and reasonable flex but extreme flex is not the be all and end all. Also some good underbody protection to help drive over obstacles is great. The other thing for any rig offroad is good gearing as it makes a big difference. The rig should be nicely balanced in it's suspension front and rear. The biggest problem with the IFS in these rigs has been the weak components that Suzuki has used and the lack of angle in the CV's but the actual design of the suspension is not that bad. They work prety well and although it may not be super flexy I think a lot of people here have actually suprised themselves what it is capable of.
