any thoughts? Need to upgrade the entire rear end..thinking dura-blues. Not sure what to get. I'd really like to get their swingarm/carrier/axle/axle accessories etc. And then move on to the front end with their stuff. But I'm not sure about the actual performance-vs-reliability between the pin-drive and the spline axle. I know the pin-drive cost considerably more, but race parts usually do...does "race" mean I can only run it a few times here and there, or can I beat on it like I do now? Dura blue says if the hubs comes loose due to the pinholes going out of round ya need to buy new ones, but what really are the chances of that? I'm thinkin a duner would benefit, but a rock crawler might want to keep the splines?
