thanks man!
I technically already have a track dolly system but its diy really badly with imperfections here and there. but I learned something to do about the wheels that slide on the track
take a look at my video and see the slight imperfections in the track set up
once i change up my wheels on my dolly hopefully it will be much smoother, may even pick up a tripod dolly for meets, cuz bringing my track is embarassing and takes forever
