Rear Axle Boggies

[booxr800]

I was wondering if anyone could tell me the advantages or disadvantages of running 2 rear boggies over 4. I know arctic cat does this. Is it as strong? I am just wondering and considering this with my new rails that Ice Age is making. They sell the axle to run two 8'' wheels. Any and all input would be great. Thanks

Wth 2 wheels it you will eliminate some stability making the sled easier to lean when on the gas and boondocking. Saves a little weight. I don't know about strength.
