Yes I have, but I have been considering some other slider's that look and should perform much better.
There are several design's out now. I'll shoot a link when I can find the one's that I really like/want.
I got my rig swapped over to the Rockshow chassis now. Available space or lack thereof is a minor concern. I've stuck my Hot axles under it for now. Still waiting on parts to get the Berg axles complete and ready for the show.
I am waiting on Axial stub axles to replace the Berg one's right from the get go. Still need the JP lockout's. And new bearings for the VP knuckles.
I'm gonna run the Eritex Heavy Comp wheels with Rovers for the next couple of months. Unless I just cant get the balance right. They have NWTT foams in them. And I probably should have been using them all along.
You can see the XtremeRC delrin links in the picture too. I will stick with them as well.
