I have Redington Sonic Pros Zip front stockingfoot bought em this past spring (2011} the Zip front kicks butt an they fit even better than my last pair of Redington Barrierflex i had since 97 or 98 i'd have to get the reciept out to verify, I wanted a pair of Simms G3 or G4's .Went an got the Redingtons, and they literally improved the cut an fit, yes that damn clip sucks but you could sand it a whisker its made of plastic an will clip to your shoestrings easier,one thing i know is once you have your gaitors clipped they stay clipped.Redington really hit the nail on the head im actually considering a second pair.
now i will be buying a pair of Simms Rivershed or Korkers Metalheads not sure yet i really like the reinforced sides of the rivershed,but the Korkers innovative sole system is a great idea as well.
I wouldn't hesitate buying another pair of Redington Sonic Pro Zip Fronts, and if you prefer the Simms G3's and even better their G4's are great too,one thing is for sure you will have extra cabbage to but other goodies if you buy the Redingtons!
