Anyone out there who has used both Cattrax and Eurotrax care to provide some comaparative insight?

I have a H21SC and have been borrowing a friends Cattrax. They work well but the time is approaching when I will need to obtain my own wheels. Plus the Cattrax are rubbing my hulls, so need to be adjusted to fit my boat better.

If you have used both, which would you favor?

The Cattrax seem to handle the 600 plus heft of my boat well enough, Eurotrax up to the task?
