Sorry harleymike, but.....I really disagree!!
Not to argue the pluses or negatives of the Ethanol game, but check out these different links.

While many of these links relate to the Marine motor side, it is still very relevent to the 2 strokes in sleds.
So for those who say they have had "no problems", good for you. Hope the luck stays. And, maybe the blend & quality of the fuels are different in your areas.
I just know that from my personal experiences that the ethanol blend here in OR has issues. In my business pickup I lost 1-1.5 MPG when the state of OR MANDATED this sh**y gas mix since Sept 07. I drive for myself 40-50k miles per year so I know my habits & how I maintane my rig. My regular mechanic that I have used for 23 years also notes what he has seen in what it has done to the vehicles he services & he concurs that the ethanol is not a good mix!!
Then, on the 2 stroke side, I lost a Phazer motor last season to the fine ethanol mix. Seems it lets a bit more moisture in the motor than should be there & got rust on a rod bearing. Even with proper storage practices this happened. I have been riding sleds & using them since 1969, so I am not stupid in that area so I am confident where the issue came from during our "post mortem" of the motor. And, jetting was NOT an issue, I run all my sleds to the FAT side. It was definately from the "solvent characteristic's" of the fuel & moisture sitting on the bearing that caused it to fail.
Then go talk a number of mechanics who get to see the issues the ethanol is causing across the board, small engines & up. We just have to learn what it does & use the proper additives & take the proper precautions when you are forced to use it as we are here in OR. Again, maybe there are better blends in different parts of the country but, what we have here is not the best one & we just adapt.
And, dont let the fuel sit for more than a few months!!!
The best fuel is the good old non blended stuff.....if ya can get it!!
Good luck with the ole Vmax !!
