I have both types of integy, new and old, and ther atomic hubs. I see no benefit with the atomic over the new style integys. And my 2 atomic hubs did not come with the needed hingepins and e clips. Whick makes them useless as finding the correct length pin and eclips is a real PITA. Hpi makes the part but it is either discontinued or not very popular.
I say stick with the integy, never heard any issues with them.
I installed a set of them recently and they fit perfectly. I cannot say anything bad about them. I have not bash tested them yet, still have a chassis to make.
