I read most of the comments in the older Speedball thread (whew) and it was mentioned about brushes and springs changing potentially from stock. What has everyone settled on? I have been running the X7 Euro cut brushes and the red springs, both from Pro lot. I guess I've been having an OK time with them but did have one issue but I'll put it up to maybe the motor not being cleaned enough (brush dust). Also learned probably a very basic fact that you shouldn't oil then endball bushing much at all as I guess oil can get on the comm and cause issues.


I know some people might consider this top secret info and that's fine but feel free to share.. I'm a newbie and only understand the basics so that's why I was using the X7 and red springs (ease of install and usage).. But maybe I'm looking for any longevity and performance as well at this point.

I use either the upgraded Pros Sot brushes or Loford Bigfoot IIs. I radius them myself to the size I want and then use a medium spring with a little extra tension.
