well now you might be wrong there! i have heard they work. or is it the other way around?
I could see 2.86 in a 3 pitch track might work, but pretty sure 3 pitch in 2.86 won't/ i might have that backwards tho
many people have multiple seasons running 3.0 tracks on 2.86 drivers with no problems. Have never heard of anyone running a 2.86 track on 3.0 drivers.
I doubt they are putting on lots of miles. It Just Don't Work Properly
