That's not going to help getting suggestions / help.

Back to the question, and the severe lack of really important info which seem to be the key here (and others are suggesting), is what is the freehub made from, Hope offers Aluminum, and Steel, if it's Alu (guessing from the issue you have, it is), this is a well know issue that cassettes (regardless of the carrier to an extent) will dig into the soft cassette splines, and cause the issues you have having, Hope offers steel freehubs, other brands have solutions, Shimano only do steel (less XTR level titanium), Novatec and others have steel reinfored splines (Novatec calls this A.B.G)

For the shifting issues with #Kontact , if your looking to 'upgrade to Shimano, that means going to 11 speed, as a 11-42 isn't made by them in 10 speed.
