What kind of springer would work best?

[amphibious drew]

Ok folks, here is a different take on a springer thread. Anyone who has driven a springer knows how amazing they are. Heck most people that have seen them understand their awesomeness. The early springer racers don't float, but work great on the track and began the niche of a niche. I personally feel that a sprung 6x6 should be where all 6-wheeler manufacturers should be attempting to evolve too.

So here is my question, what's the best design for a springer. Whipper has made an outstanding version that delivers nothing but grins from ear to ear just sitting behind the sticks of one. His suspension system utilizes a design similar to what is found in dune buggies. Mudd-Ox went a different route utilizing a more agricultural style design. I've thought about a 6 swing are system with 4 going to the back and 2 to the front. It is just a thought, but I really hate the idea of external chains.

Please use this thread to help brainstorm design ideas. If we could keep the discussions of pro's and con's of design limited to facts that would be great. Although a springer is not in my near future, when my gotcha and 980 are done, and my Attex is redone, I may decide to attempt and conquer building one. For discussion sake, I want it to still be amphibious.

I think the Hustler that was home built looked good and should be low buck, have not heard results and not sure if trailed yet.
All of the designs have different travel and load ratings so that may come to play in your final design as well as width.

The swing arm system would be a superior design. Early VW busses used a "pod" on the end of the axle with gear reduction that would take the place of chains OR lighten the design w/ chain. The enclosure would need to be water tight and oil tight. The big drawback as I see it is the expense of production.
Having all the arms swing backwards would improve the ride at higher speeds.
Here is a similar design. [IMG][/IMG]
