I am not too sure regarding the Dubro gear. In fact, if the gear deforms on landing its a good thing- it absorbed some of the shock of the landing. However, if it keeps deforming, even after a good landing, thats a nuisance.

I think CF will be worse off in that it will shatter after a less than perfect landing, so I am told. I had obtained these but didnt use them for this reason
