I'm one of these guys that runs without a sway bar.
I have a 2001 XC 500 Mod sled. Performance exhaust, Can, Reeds, Boost-Bottle and a right Sided late model red trailing arm with updated performance emblems. It also has a custom crank by Ross Schmidt. We cut the sway bar out of that thing. It really sits into the turns after that. So, I would have to tell you it's something to think about.
I love it and would never go back. But... that is with the Edge chassis.
I also have a 2010 IQ 600 with a newly extended skid/tunnel (all custom) to handle a 144'' track. I have not yet cut the sway bar out. I hesitate with the IQ. They are a bit more nimble than the edge and I wouldn't want that nimbleness to translate to instability in the turns.
The last thing to consider... you ride Iron County. In one weekend you can go from icy conditions with blown out corners on the trails to Steep and Deep Powder.
I would ride without the sway bar. You'll probably get more compliments, ooohs and aahhs, and attention from the ladies when you're at the bar. Especially in Iron County.
