I did use the Hutchinson Sealant (recommended by Shimano) and have had no corrosion whatsoever. From what I understand there was an issue with the 7000 series Dura Ace wheels and Stans Sealant. I have the Ultegra 6700 wheels which appear to be anodized on the inside to inhibit the corrosion issue. I'm not sure which wheel you have but I would hope Shimano has begun to anodize all of their road tubeless wheels these days. They are releasing the C35's in a tubeless version for 2015 and I plan to get a set but only if they're anodized. I say give it a try, the industry is headed that way so you might as well get on board. Everyone I have met that has gone tubeless swears they will never switch back to a std clincher, on the other hand there's a lot of people who are afraid to take the plunge because they have heard all the horror stories from the guys that had nothing but problems. The guys having trouble were simply doing it wrong using the wrong wheels, tires, or trying to do a ghetto setup which at 100+ psi is a recipe for disaster. You have the proper wheel so all you need is a "road tubeless" tire, stem (should have come with the wheel), and a small bottle of sealant. I just ordered a Fusion 3 from Performance during one of their 20% off flash sales and it was $63.00 delivered to the store. Either way, tubed or tubeless you'll be fine with the wheel they sent you but if you don't try tubeless you will always be asking yourself (as your riding) how much better would the ride be if I had tried it?
