The Rio system is a good system and I have never had a Rio loop give me problems. The one complaint I have is that the Type VI tip which comes with the Windcutter tips package does not get down like I think it should. I still use it for times when I don't want to be dredging but have homemade tips for those times I do. I know one of the posters here has simply purchased the Rio tip in a larger line size (11 weight ?)and is happy with the performance.
