We've never had a problem with either wheel, including direct impacts on 6" plaction wheels going over the bumps in 2010. I'll also note that we use lock nuts in lieu of Loctite.

Plactions are nice because they're very quick to put together and they're inexpensive. We've had some slight problems with inner bearing housing flex after several competitions, but that was after 4 competitions.

IFI's are nice because once they're put together, you'll never have a problem with the wheel itself. Their assembly is made easier by substitution of Phillips head machine screws in place of the button head bolts that constantly strip. They're a nice weight for their strength. They also come in 1.5" and 2.0" widths for only slightly more weight, whereas the Plaction wheels need PVC and longer bolts to achieve greater width.
